The earliest known Joe Dimaggio signed Baseball Bat. The bat is a game used Louisville Slugger bat that was used by baseball player Jim Brown in 1938 and 1939. It is signed in steel tip fountain pen by a young 24 year old Joe Dimaggio. The bat is inscribed "St. Petersberg March 25, 1939" indicating that Joe signed this bat during Spring Training in Florida at the start of the historic 1939 season where the Yankees went on to win the World Series. Comes with full letter COA from JSA as well as a PSA DNA COA detailing the history and game use of the bat. A Hall Of Fame worthy relic from one of Baseball's greatest players.
