The cards in this 572-card set measure 2 1/2" by 3 1/2". The 1959 Topps set contains bust pictures of the players in a colored circle. Card numbers 551 to 572 are Sporting News All-Star Selections. High numbers 507 to 572 have the card number in a black background on the reverse rather than a green background as in the lower numbers. The high numbers are more difficult to obtain. Several cards in the 300s exist with or without an extra traded or option line on the back of the card. Cards 199 to 286 exist with either white or gray backs. There is no price differential for either colored back. Cards 461 to 470 contain "Highlights" while cards 116 to 146 give an alphabetically ordered listing of "Rookie Prospects." These Rookie Prospects (RP) were Topps' first organized inclusion of untested "Rookie" cards. Card 440 features Lew Burdette erroneously posing as a left-handed pitcher. Cards were issued in one-card penny packs or six-card nickel packs. There were some three-card advertising panels produced by Topps; the players included are from the first series. Panels which had Ted Kluszewski's card back on the back included Don McMahon/Red Wilson/Bob Boyd; Joe Pignatano/Sam Jones/Jack Urban also with Kluszewski's card back on back, Strips with Nellie Fox on the back included Billy Hunter/Chuck Stobbs/Carl Sawatski; Vito Valentinetti/Ken Lehman/Ed Bouchee; Mel Roach/Brooks Lawrence/Warren Spahn. Other panels include Harvey Kuenn/Alex Grammas/ Bob Cerv; and Bob Cerv/Jim Bolger/Mickey Mantle. When separated, these advertising cards are distinguished by the non-standard card back, i.e., part of an advertisement for the 1959 Topps set instead of the typical statistics and biographical information about the player pictured. The key Rookie Cards in this set are Felipe Alou, Sparky Anderson (called George on the card), Norm Cash, Bob Gibson, and Bill White.
