"It's the only picture I've taken ever in my life that, when I look at it even 50 years later ... there isn't a single thing I would change."

This photo of actress Marilyn Monroe was taken by Douglas Kirkland in 1961 and given to Leifer. "It's a very famous photo that he shot," Leifer said. "Doug and I are still very good friends. Over the years I swapped (photos) with him a half a dozen times."

I wanted Pulitzer Prize winners in my collection; this photo was a finalist in 1990."

Leifer is renowned for his sports photography, but his career has been more than that. In 1991, he took this photo of US jets flying over burning oil fields in Kuwait. "That is a particular favorite of mine," he said. "Life magazine, during the first Gulf War, decided to go weekly again -- they hadn't published a weekly magazine since 1972. I was hired, not to shoot, but to go to Saudi Arabia and be a picture editor and edit film from our photographers in the field. When the war was over, the Marines offered me the opportunity to fly over what had been the battlefield. Nobody showed up for it except for me and my assistant. I was up in a Marine C-135 refueling plane. Those F-18s are refueling. I asked if we could go over the oil fields, and they did."

Muhammad Ali poses at a Miami gym in 1960. "Photographers don't usually get very close to their subjects," Leifer said. "Ali and I had a great relationship for many years when he was fighting, but I never had so much as a cup of coffee with him in those years. When he ended his career, probably 10 years later, we really became quite close. He was just a wonderful guy. I was always a huge fan. For one, he was the most colorful athlete I ever saw. Quite frankly, if you are a young photographer, young writer, young TV person, he made everybody look good. Your boss would think, 'Wow, what great stuff you've got,' not realizing how easy it was with a subject like Ali. I miss him."

I spent all day up above the Sail. I was lucky enough to be able to do it."

Cuban leader Fidel Castro lights Leifer's cigar in 1984. This photo is not part of the auction. "We did a pre-Olympic photo essay for Time magazine," Leifer recalled. "The idea was to shoot photographs of top athletes from all around the world from each country -- potential Gold Medal winners. The idea was to photograph them in front of (a) picture postcard of their country. The front of the magazine was Carl Lewis. I photographed him in front of the Statue of Liberty. I went to the Cubans and said I would like to do one of the great Cuban athletes ... a boxer named Teofilo Stevenson. ... Unlike the other countries, the picture postcard of Cuba was Fidel Castro. They eventually approved the shoot. For years, I have always ended every session with a photograph of me and the subject. One day you get older and you want to look back at this sort of thing. I asked Fidel Castro when we finished our shoot, 'Can I get a picture with you?' When he was ready to pose, I said: 'I've got a particular picture in mind. I would love to have you lighting my cigar.' "
