The 1957 Topps football set contains 154 standard-size cards of NFL players. Cards were issued in penny, nickel and cello packs. Horizontally designed fronts have a close-up photo (with player name) on the left and an in-action pose (with position and team name) to the right. Both have solid color backgrounds. The card backs were printed in red and black on gray card stock. Backs are also divided in two with statistical information on one side and a cartoon on the other. The Rookie Cards of Johnny Unitas, Bart Starr, and Paul Hornung are included in this set. Other notable Rookie Cards in this set are Raymond Berry, Dick "Night Train" Lane, Tommy McDonald and Earl Morrall. The second series (89-154) is generally more difficult to obtain than the first series. A number of cards (22) from the second series are much easier to find than the other 44, making those double prints (DP). It's thought that the John Unitas Rookie card is among the 22-DPs. An unnumbered checklist card was also issued with this set. The checklist card was printed in red, yellow, and blue or in red, white, and blue; neither variety currently is recognized as having any additional premium value above the price listed below. There also were produced several three-card advertising panels consisting of the card fronts of three players with ad copy on the reverse of the top two cards and a player's cardback at the bottom. The complete set price below refers to the 154 numbered cards minus the unnumbered checklist card.
