100% Authentic Hand Signed Baseball by Canseco and McGwire-the BASH BROTHERS!

The ball that you see in the scans is the one that you will receive. Mark will not sign items that are signed by Jose, so these items are tough to complete!

Ball is an official MLB Ball- ROMLB Leather ball like the one that they play with in the majors-the autograph will nice for years to come, not like on those cheap ball park baseballs with vinyl or rubber covers!
