Muhammad Ali Vs. Sonny Liston, Neil Leifer, 1965
In Lewiston, Maine, on May 25, 1965, a 23-year-old heavyweight boxing champion, named Muhammad Ali, squared off against 34-year-old Sonny Liston, the man he’d snatched the title from the previous year. One minute and 44 seconds into the first round, Ali’s right fist connected with Liston’s chin and Liston went down. Leifer snapped the photo of the champ towering over his vanquished opponent and taunting him, “Get up and fight, sucker!”
