In 1957 Topps created the modern day card by reducing the size of cards to current standard 2-1/2 x 3-1/2 inches. Topps also increased the set to 154 players and dramatically changed card format to a horizontal split-card. Player selection was awesome with (31) future Hall-of-Famers. 1957's top rookies were Bart Starr, Johnny Unitas & Paul Hornung. The only variation is card #58 Willard Sherman.

Competition was raging between Topps and Bowman in 1953 and 1954 leading to problems with both companies sets. Bowman caused Topps to missing 6 cards in 1953 with Topps getting revenge by signing Ted Williams to an exclusive contract in 1954. Bowman then had to pull Ted Williams card #66 from their set shortly after they started printing, replacing it with Jimmy Piersall, who also was on card #210 making the 1954 Bowman Ted Williams #6 one of 50's scarcest cards.

Perhaps distracted by it's competition with Topps, the 1954 Bowman set was filled with errors and variations. Nearly 20% (40/224 cards) had some sort of variation, with some having more than 2.

The St. Louis Browns recent move to Baltimore also made things interesting. Bowman's artists had no idea what an Orioles jersey would look like - so they just madeone up.
