The cards in this 250-card set measure approximately 2 5/8" by 3 3/4". Each of the cards in the 1954 Topps set contains a large "head" shot of the player in color plus a smaller full-length photo in black and white set against a color background. The cards were issued in one-card penny packs or five-card nickel packs. Fifteen-card cello packs have also been seen. The penny packs came 120 to a box while the nickel packs came 24 to a box. The nickel boxes had a drawing of Ted Williams along with his name printed on the box to indicate that Williams was part of this product. This set contains the Rookie Cards of Hank Aaron, Ernie Banks, and Al Kaline and two separate cards of Ted Williams (number 1 and number 250). Conspicuous by his absence is Mickey Mantle who apparently was the exclusive property of Bowman during 1954 (and 1955). The first two issues of Sports Illustrated magazine contained "card" inserts on regular paper stock. The first issue showed actual cards in the set in color, while the second issue showed some created cards of New York Yankees players in black and white, including Mickey Mantle. There was also a Canadian printing of the first 50 cards. These cards can be easily discerned as they have "grey" backs rather than the white backs of the American printed cards. To celebrate this set as the first Topps set to feature Ted Williams, his visage is also featured on the five cent box. The Canadian cards came four cards to a pack and 36 packs to a box and cost five cents when issued. Read Less »
