An exhibit that opened Monday at the Gordon Parks Foundation features images of the world heavyweight champion boxer from sessions with Parks in 1966 and 1970. The four images shown here were never printed during Ali's lifetime.
After converting to Islam and renouncing his given name Cassius Clay as a "slave name," Ali declared himself a conscientious objector to the Vietnam War. According the foundation, Parks hoped to "rehabilitate Ali’s image by showing the human side of the smooth-talking fleet-footed boxer who often came off as supremely confident, even arrogant, in his public appearances."
