Topps changed their style in 1955 and issued a horizontal card. The fronts are similar to the 54 set using a lot of the same images. Backs are numbered and have the players bio and stats. High numbered cards 161-210 are scarce. Because of the competition with Bowman the 1955 Topps baseball card set is missing 4 cards. The original players slated for those cards signed exclusive contracts with Bowman. The set consists of 206 baseball cards numbered 1-210. Cards not issued are: 175, 186, 203 and 209.
