This is an actual, full size rubber home plate most likely purchased at a sporting goods store. 400 game winning pitcher and Japanese career strikeout record holder, Masaichi Kaneda, wrote a very large autograph directly on the plate in black marker, and then added his uniform number "34". The autograph is approximately 1 foot long! This is certainly a unique piece.
Size: 17" x 16 1/2" x 1/4". Weight: 5 lbs.
Condition: Minor wear. The signature is a bold 9 out of 10.
