The cards in this 206-card set measure approximately 2 5/8" by 3 3/4". Both the large "head" shot and the smaller full-length photos used on each card of the 1955 Topps set are in color. The card fronts were designed horizontally for the first time in Topps' history. The first card features Dusty Rhodes, hitting star and MVP in the New York Giants' 1954 World Series sweep over the Cleveland Indians. A "high" series, 161 to 210, is more difficult to find than cards 1 to 160. Numbers 175, 186, 203, and 209 were never issued. To fill in for the four cards not issued in the high number series, Topps double printed four players, those appearing on cards 170, 172, 184, and 188. Cards were issued in one-card penny packs or six-card nickel packs (which came 36 packs to a box) and 15-card cello packs (rarely seen). Although rarely seen, there exist salesman sample panels of three cards containing the fronts of regular cards with ad information for the 1955 Topps regular and the 1955 Topps Doubleheaders on the back. One panel depicts (from top to bottom) Danny Schell, Jake Thies, and Howie Pollet. Another Panel consists of Jackie Robinson, Bill Taylor and Curt Roberts. The key Rookie Cards in this set are Ken Boyer, Roberto Clemente, Harmon Killebrew, and Sandy Koufax. The Frank Sullivan card has a very noticable print dot which appears on some of the cards but not all of the cards. We are not listing that card as a variation at this point, but we will continue to monitor information about that card.
