Before the instant gratification of deleting unwanted photos and the immediacy with which you can post desirable shots on social networks, people had to wait for their film to be developed in order to see what they had actually taken.

Sometimes their photos turned out to be awkward, unprofessional or even offensive and were left behind. (Also, if the negatives were considered risqué, they wouldn’t be developed.)

Michael Lesy, a graduate student in the 1970s, had photography as his main interest. His friend was a motorcycle driver who took film from drugstores to a factory.

‘What we used to do for a while… is raid the dumpsters,’ Lesy told DailyMail.com.

He amassed an archive during a 1971 summer in San Francisco.

“Every week, for the four weeks of summer, we took home any snapshots that we found,” he said. They were in the trash because the machines that made them—duplicates, triplicates, quadruplicates—made them faster than the people on the line could stop them,’ he wrote in his new book, Snapshots 1971-77.

“We estimated that we took home seven thousand per week. I would spend hours looking through them. Some I kept, most I threw away.

Lesy was back in Cleveland years later and another opportunity presented itself for photos. He met a friend who knew a drugstore owner who was unsure what to do with the photos people didn’t pick up.

Lesy waited 50 year to publish his snapshot collection. “I always had it together. He said that this book could be made at any moment, but that there was a high legal risk.

He wrote, “Fifty years later, nothing and everything has changed.”             

During the summer of 1971, Michael Lesy was staying with a friend, who was a motorcycle delivery boy who ferried film from drugstores to be processed at a factory. 'Every week, for four weeks during the summer, we took home whatever snapshots we found. They were in the trash because the machines that made them¿duplicates, triplicates, quadruplicates¿made them faster than the people on the line could stop them,' he wrote in his new book, Snapshots 1971-77. In the image above, Lesy noted the man's holster and his gun, and that he was likely a detective. 'Look beneath the surface,' Lesy told DailyMail.com, 'that is what this book insists upon'

Michael Lesy stayed with a friend in 1971. He was a motorcycle courier boy who transported film from drugstores and to a factory. We took home all the snapshots we could find every week for four weeks. They were in the trash because the machines that made them—duplicates, triplicates, quadruplicates—made them faster than the people on the line could stop them,’ he wrote in his new book, Snapshots 1971-77. The man’s holster, as well as his gun, are both noted by Lesy in the above image. This suggests that he was probably a detective. DailyMail.com’s Lesy said that he recommends looking beneath the surface.

Lesy estimated that he took home around 7,000 images a week. 'I'd spend days looking through them. Some I kept; most I threw out,' he wrote in Snapshots 1971-77.  When he went back to graduate school in Wisconsin after that summer in San Francisco, he took hundreds of snapshots with him. He told DailyMail.com that he was very selective in editing. 'I understood them as forming an archive¿an archive of the present,' he wrote in his new book.

Lesy estimated that Lesy took home about 7,000 images per week. I spent days looking through them. Some I kept; most I threw out,’ he wrote in Snapshots 1971-77.  He took hundreds of photos with him when he returned to Wisconsin to study at graduate school. DailyMail.com he said that he was very selective when editing. ‘I understood them as forming an archive—an archive of the present,’ he wrote in his new book. Above, Lesy and a married couple. Note the groom’s foxy smile.

Vacation pictures used to fill albums instead of social media platforms. Lesy noted the body posture of the family above. 'The boy is having none of this,' he said, adding that his mom links her arm with his anyway. The daughter is holding herself up and she leans against her father. He wrote in Snapshots 1971-77: 'I realized something important: the people who made the pictures were insiders, not outsiders. I also understood that the people behind the camera made, without intending to, pictures of themselves'

Instead of using social media platforms to share vacation photos, albums were used to store them. Lesy noticed the family’s body posture in the photo above. “The boy is not having any of this,” he said, adding that his mom still links his arm with his. The daughter is standing up and leans against her father. Snapshots 1971-77, he wrote: “I realized something important: The people who made the photos were insiders, and not outsiders.” I also understood that the people behind my camera took photos of me, even though they weren’t intended to.

'It's like a Madonna, I thought,' Lesy said about the image above of a young mother with her baby. The snapshots that he found either because they were never picked up or because they were duplicates offered a look into his fellow citizens' lives. 'Looking through the snapshots, fresh from the trash, was like being blasted by a firehose of information, soaked and pinned to the wall by it. It was intimate, domestic, close-up information that I could never have known otherwise,' he wrote in Snapshots 1971-77

Lesy said, “It’s almost like a Madonna, I thought,” about the above photo of a young mother holding her baby. He was able to see the lives of his fellow citizens through the snapshots he found, whether they were duplicates or never picked up. “Looking through the snapshots fresh from the trash was like being blasted with a firehose full of information, soaking and pinned to a wall by it. It was intimate, domestic, close-up information that I could never have known otherwise,’ he wrote in Snapshots 1971-77

Lesy stated that his father’s family was not from Warsaw.

‘In 1921, my family immigrated to America. They settled in Cleveland. After World War II began in Poland, the SS forced all the residents of my father’s village into the town’s large wooden synagogue. They first forced them to take down the synagogue’s Creation frescoes using their fingernails. They locked the doors and set fire to everyone.

His parents, who had been married for 60 years each, waited until the war ended to have a child.

DailyMail.com was told by him that after the war, there had been an effort to capture humanity. He said, “It was using cameras to bear witness.”

During the Great Depression, the US government paid photographers for photos of people. This program became known as Farm Security Administration. The government wanted to gain support for the New Deal spending and revive the farm economy. Lesy compared the portrait of the American people who emerged to the Great Pyramids and the Pantheon. DailyMail.com’s Lesy said that it was a collective effort to pay tribute to existence.

Lesy was also inspired to use Farm Security Administration images by Henri Cartier-Bresson. Henri Cartier-Bresson was a famous photographer who is known for the decisive moment’. He also helped create Magnum and the important 1955 Family of Man exhibition in the Museum of Modern Art.

He said, “I was carrying them in my head.”

He was the only child of Jewish immigrants. He was going to graduate school to study American history. He stated that the Holocaust smoke was still in the air.

In 1971, he visited Berkeley to see his friend, who was a delivery worker.

‘Looking through the snapshots, fresh from the trash, was like being blasted by a firehose of information, soaked and pinned to the wall by it,’ he wrote in Snapshots 1971-77, which is published by Blast Books.

“It was intimate, intimate, and close-up information that was not available to me in any other way.”

After that summer in San Francisco, Lesy took hundreds of snapshots and went back to graduate school in Wisconsin. While studying American history, he met Paul Vanderbilt, an archivist and photographer. Vanderbilt told him about an archive for a town called Black River Falls. It included images taken by photographer Charles Van Schaick. This became Lesy's dissertation, which would turn into his first book, Wisconsin Death Trip. 'It was very controversial,' he said of his 1973 book

Above, three well-dressed men attending a party. Lesy noticed the dignity and formality in the image. After spending a summer in San Francisco, Lesy took hundreds more photos and returned to Wisconsin for graduate school. Paul Vanderbilt was an archivist and photographer that he met while studying American History. Vanderbilt told him of a Black River Falls archive. It contained photographs taken by Charles Van Schaick. This was Lesy’s dissertation that would become his first book, Wisconsin Death Trip. His 1973 book, Wisconsin Death Trip, was a controversial one.

Lesy said the above picture of a man smoking weed in front of the U.S. Capitol is 'a protest photograph. It's a rebellious image.' In 1971, the United States was still embroiled in the Vietnam War and the trials of those involved with the 1968 My Lai Massacre and the shocking 1969 murders of actress Sharon Tate, who was pregnant, and others at the hands of Manson's followers, were ongoing

Lesy said that the above photograph of a man smoking pot in front the U.S. Capitol is a protest photo. It’s a rebellious photo. The United States was still involved in Vietnam War. In 1971, trials of those who were involved in the 1968 My Lai Massacre, the shocking 1969 murders by Manson’s followers of Sharon Tate and other victims were ongoing.

'Every picture has a backstory ¿ has a surface and a depth,' Lesy said about the snapshots. He pointed out the written reminders on the chalkboard behind the nun in the above image. In addition to photographs taken during the Great Depression in the 1930s, Lesy was also inspired by Henri Cartier-Bresson, a famous photographer known for the 'decisive moment' and one of the founders of Magnum, and an important 1955 Family of Man exhibition at the Museum of Modern Art. He told DailyMail.com: 'I was carrying those in my head'

‘Every picture has a backstory – has a surface and a depth,’ Lesy said about the snapshots. He pointed out the written reminders on the chalkboard behind the nun in the above image. Henri Cartier-Bresson is a famous photographer, known for his ‘decisive moment’. He also inspired Lesy to take photographs during the Great Depression of 1930s. Magnum was also founded by him. Magnum also had an important 1955 Family of Man exhibit at the Museum of Modern Art. DailyMail.com he said that he was carrying those thoughts in his head.

Lesy said that some of the images in the collection were obscene. He noted that when a person took their negatives to a drugstore or another business, like a Fotomat, to develop the film, there were times when they refused to print the photo. The image above, he said is very sweet, loving, affectionate and erotic. He noted that it seems she created mise en scene and all that was missing was a bear skin rug

He said that the image above is sweet, loving, affectionate, and erotic. He noted that it seems she created mise en scene and all that was missing was a bear skin rug

DailyMail.com was informed by Lesy that these photographs were a truer witness’ than the Farm Security Administration photos of the country. He also shared details about his fellow citizens.

1971 was still a time when the United States was involved in the Vietnam War. The trials of those who were involved with the 1968 My Lai Massacre, the shocking 1969 murders, of Sharon Tate (who was pregnant) and other victims of Manson’s followers were ongoing.

After spending the summer in San Francisco Lesy took photos and returned to Wisconsin for graduate school. Paul Vanderbilt was an archivist and photographer that he met while studying American History. Vanderbilt told him of a Black River Falls archive. It also contained images taken Charles Van Schaick, photographer.

This was Lesy’s dissertation. It would become his first book, Wisconsin Death Trip. They were divided when he presented it his dissertation committee. His 1973 book, he stated, was very controversial. 

Wisconsin Death Trip is now a seminal book and a cult-classic. A documentary based on the book, was released in 1999.

In the late 1970s Lesy was in Cleveland again and a friend, who was then an attorney, had a client who owned his own drugstore. Lesy explained that people sometimes forget to pick their photos up or don’t want the images anymore. Unclaimed photos were eventually thrown away.

Lesy, who has been looking at photographs for decades and has written several books, said snapshots are often dismissed as ‘trash or trivia,’ but he pointed out that ‘every picture has a backstory – has a surface and a depth. If you pause for a moment, you will see more.

‘Look beneath the surface… that is what this book insists upon.’

There are several rituals that have changed around photography since the ubiquity of cameras on phones and the arrival of other technology. Lesy noted that families used to sit down with albums to talk about the photographs and the past. For example, a child might ask a parent who someone is in a photograph, he explained. 'What they leave out is often as important as what they leave in; what they emphasize and what they minimize can be equally revealing,' he wrote in his new book, Snapshots 1971-77, about the images.

Photography has seen many changes since the advent of smartphones with cameras and other technology. Lesy mentioned that in the past, families would sit down with an album to talk about the past and their photographs. He explained that a child could ask a parent about the identity of someone in a photo. ‘What they leave out is often as important as what they leave in; what they emphasize and what they minimize can be equally revealing,’ he wrote in his new book, Snapshots 1971-77, about the images. Above, children wearing pirate hats at their birthday party

Lesy said the snapshot above reminded him of the 1990 movie Goodfellas. He wondered who was taking the picture and if it was law enforcement. Lesy told DailyMail.com he was a self-taught photographer and many people were picking up a camera while he studied at Columbia. 'It was in the air.' He carried a 35mm, single-lens reflex camera and aspired to be a documentary photographer. Lesy has written 13 books, some of which are based on archival photography, like Wisconsin Death Trip

Lesy said that the above photo reminded him of Goodfellas from 1990. He wondered who took the picture and if law enforcement was involved. DailyMail.com’s Lesy said that he was a self-taught photographer. Many people were using cameras while he was studying at Columbia. It was everywhere. He carried a 35mm, single-lens reflex camera and aspired to be a documentary photographer. Lesy has written 13 books. Some of these books are based upon archival photography such as Wisconsin Death Trip.

In the late 1970s, Lesy was back in his hometown of Cleveland and another opportunity for snapshots cropped up. Through a friend, he met a drugstore owner who didn't know what to do with the pictures people did not pick up. 'Drugstores in Cleveland threw away unclaimed snapshots after several weeks of waiting for customers to pick them up. I never found out if the drugstores had an official time limit,' he wrote in Snapshots 1971-77. 'I suspect that when they ran out of space to keep them behind the front counter, they threw the pictures into a bag and¿once the bag was full¿threw the bag away.' Above, a 'very hip' woman, Lesy said

Above, likely a Memorial Day celebration, Lesy said. 'Seen through the eyes of an outsider like me, the snapshots looked in four directions at once: out at the subject, back at the photographer, inward at their assumptions and beliefs, and then out, beyond them, at the world in which they thought they lived,' he wrote in his new book

Above, a Memorial Day celebration, Lesy stated. He wrote that he saw the photos through the eyes of an outsider such as himself. The snapshots looked in four directions simultaneously: out at the subject and back at the photographer. Inwardly at their assumptions and beliefs. Finally, out, beyond, at the world in the which they believed they lived.

'I always had it together,' Lesy told DailyMail.com. 'This book could have been made at any time.' However, he noted there was more of a legal risk if he published before now. 'Times changes everything,' he said. Above, the cover of his book. Lesy explained that after Wisconsin Death Trip, which sold well, he wrote more books. 'For the next twenty years, from one book to the next, I traveled throughout the United States giving lectures, each illustrated with hundreds of archival images. I don't remember when I made color slides of the snapshots I'd found in San Francisco. Now and then in my travels, I'd show them to audiences,' he wrote in Snapshots 1971-77. 'The purpose of those slide shows¿and now the purpose of this book¿was to show images whose meanings appear obvious, but which are riddles with more than one answer'

Lesy stated that he always had it all together. “This book could have been written at any time.” However, he pointed out that there was a greater legal risk if the book was published before now. He stated that “Times change everything.” Above is the cover of his book. Lesy explained that his book Wisconsin Death Trip was a success and he began writing more books. “For twenty years, I traveled the United States giving lectures. Each lecture was illustrated with hundreds upon hundreds of archival photos. I don’t recall when I made color slides from the San Francisco snapshots that I found. He wrote Snapshots 1971-77 that he would show them to people every now and again during my travels. ‘The purpose of those slide shows—and now the purpose of this book—was to show images whose meanings appear obvious, but which are riddles with more than one answer’
