In 1951, Bowman increased the number of cards in its set for the 3rd consecutive year when it issued 324 cards. The cards are, like 1950, color art reproductions of actual photographs but now measure 2-1/16" by 3-1/8" in size. The player's name is situated in a small, black box on the card front. Several of the card fronts are enlargements of the 1950 version. The high-numbered series of the set (#'s 253-324), which includes the rookie cards of Mantle and Mays, are the scarcest of the issue.
