Muhammad Ali in 1967, the year he turned 25. (Muhammad Ali was born on January 17 of 1942, so he was almost certainly 25 when this shot was taken.) The photo, by Ira Rosenberg for the New York World Journal Tribune, is now housed in the U.S. Library of Congress. 1967 was the year that Muhammad Ali refused induction into the U.S. Army, leading to him being stripped of his heavyweight title and being banned from boxing in the United States. His conviction on charges of refusing induction was eventually overturned by the U.S. Supreme Court.
