It was the Fight of the Century. On March 8, 1971, Muhammad Ali and Joe Frazier stepped into the ring at Madison Square Garden to battle for the title of Undisputed Heavyweight Champion of the world—and a then-record $2.5 million purse.
In honor of the match's 40th anniversary, LIFE has published a series
of never-before-seen images taken by staff photographer John Shearer. The three that appear below document the progression of the fight: First, the press' infatuation with the charismatic presumed winner, Ali; second, Ali's flagging energy midway through the bout; and finally, Frazier's quiet satisfaction at beating Ali by unanimous decision in 15 rounds.
