Perhaps the greatest boxing rivalry ever extended beyond the ring in this candid photo of Muhammad Ali disrupting Joe Frazier's preparation routine before their 1971 "Fight of the Century" in New York City. The two Hall of Famers went on to battle three times, although this was the first of the match-ups, on March 8, 1971 at Madison Square Garden. That fight was won by Frazier, who handed Ali his first-ever professional loss. The 35x30" matted and framed photo by official Garden photographer George Kalinsky is from the original negative and printed on the finest paper. It signed by all three men and features the last of the large signatures for Ali. The plaque at the bottom reveals it is part of an extremely limited edition #82/250. The two champs would revisit their rivalry in both 1974 and '75, with Ali exacting revenge in both.
