Hammer down the winning bid, for this “Hammerin’ Hank” Greenberg boldly signed baseball. A vintage OAL/MacPhail model in (NM) state, this lightly toned ball is signed on the sweet spot by Greenberg with (“9.5”) potency, by means of a black felt-tip pen. As we approach the 40th anniversary of Greenberg’s 1986 demise, this is an excellent time to add this important Hall of Famer to your collection. An accompanying Al Kaline Collection Letter of Provenance is signed by Mark Kaline, and states this ball belonged to his father. Full LOA from Beckett Authentication Services. Opening Bid $900.
