The cards in this 320-card set measure approximately 2 1/2" by 3 3/4". The Bowman set of 1955 is known as the "TV set" because each player photograph is cleverly shown within a television set design. The set contains umpire cards, some transposed pictures (e.g., Johnsons and Bollings), an incorrect spelling for Harvey Kuenn, and a traded line for Palica (all of which are noted in the checklist below). Some three-card advertising strips exist, the backs of these panels contain advertising for Bowman products. Print advertisments for these cards featured Willie Mays along with publicizing the great value in nine cards for a nickel. Advertising panels seen include Nellie Fox/Carl Furillo/Carl Erskine; Hank Aaron/Johnny Logan/Eddie Miksis; Bob Rush/Ray Katt/Willie Mays; Steve Gromek/Milt Bolling/Vern Stephens, Russ Kemmemer/ Hal Jeffcoat/Dee Fondy and a Bob Darnell/Early Wynn/Pee Wee Reese. Cards were issued either in nine-card nickel packs or one card penny packs. Cello packs containing approximately 20 cards have also been seen, albeit on a very limited basis. The notable Rookie Cards in this set are Elston Howard and Don Zimmer. Hall of Fame umpires pictured in the set are Al Barlick, Jocko Conlon and Cal Hubbard. Undated five cent wrappers are also known to exist for this set.
