Topps set in 1957 added some new innovations. The fronts are color photos of the players. Backs are numbered and for the first time have complete player stats. Card #265-352 are scarce. Also, the cards issued this year were smaller than years prior. The new smaller size would set the standard for baseball cards issued even today. The 1957 set is a popular set amongst collectors with its simple yet attractive design, not to mention the set is also loaded with rookies and star power.
