The mark they left on the sport of boxing is unquestionable and equally impressive is the mark each has left on these terrific display pieces. Jack Johnson (7/10), Primo Carnera (7/10), Gene Tunney (8/10) have each signed their EX, 3.5”x5.5” postcard or exhibit card in black pen while Ezzard Charles (8/10) has done the same in blue ink. Joe Louis’ (8/10) signature (pencil) has been nicely matted along with an image of Joe in his stance, measures 9.5”x15”. Jess Willard’s (8/10) blue ink signature is mounted in the same attractive fashion measuring 11”x16”.
