Reach OAL baseball signed by the six umpires of the 1973 All-Star game. The ball includes a tough signature of Hall of Famer Nestor Chylak along with the incredibly popular Ron Luciano. Other signatures include Ken Burkhart Larry Barnett Bill Williams and Bob Engel. Though the ball is relatively clean with just a few minor spots of staining the signatures themselves are somewhat faded. A small stain is visible over Chylak's signature probably the largest stain on the ball. COA from James Spence Authentication.
