Issued by Gum, Inc., this set includes 75 numbered cards (two consecutive numbers per card) featuring 150 players. The blank-backed cards measure 3-1/8" X 2-1/2" and feature black-and-white photos of the players, some in horizontal format, some in vertical. The last 50 cards in the series are scarcer than the early numbers. Cards which have been cut in half to form single cards have little collector value. The example above is in NM-MT condition and pictures HOFer Luke Appling.
