Tony Canzoneri Signed 1925 Exhibit. Incredible signed item by Boxing Hall of Famer and the Three-Division world Champion Tony Canzoneri. Along with Henry Armstrong and Barney Ross, Canzoneri is the only champion in history allowed to hold two or more titles simultaneously. Signed items by the famed NY fighter are tough to come across due to his passing away of a heart attack at the age of 51 in 1959. The exemplar offered here is one of the nicest known in the hobby as it is boldly penned on a scarce 1925 Blue Exhibit postcard. A great addition to any boxing or Hall of Fame autograph collection.
