Floyd Patterson was known as "the Gentleman of Boxing" outside the squared circle, but he was one of the most feared and respected heavyweights in game once the bell sounded. This nicely packaged certificate represents his induction into the International Boxing Hall of Fame on June 9, 1991. Presented in its original box, the enclosed certificate references the ring which accompanied this distinction (not included). Patterson won 55 professional bouts on the way to his two heavyweight championships. LOA from Patterson family.
