Argentine Heavyweight Oscar "Ringo" Bonavena flexs his muscles and his opponent Joe Frazier, behind him at center, seems amused as they weigh in September 21, 1966 at the New York State Athletic Commission for their ten round bout. The match is scheduled for the evening at Madison Square Garden. The man at left is Ed Dooley, commission chairman. Frazier, of Philadelphia, the 2-1 favorite, weighed 203 1/2 pounds to Bonavena's 205. (AP Photo).
