In the early 1930s, production soared, starting with the 1932 U.S. Caramel set. The popular 1933 Goudey Gum Co. issue, which included cards of Babe Ruth and Lou Gehrig, best identifies this era. In contrast to the economical designs common in earlier decades, this card set featured bright, hand-colored player photos on the front. Backs provided brief biographies and personal information such as height, weight, and birthplace.

Individual cards measured , which Goudey printed on 24-card sheets and distributed throughout the year. The bulk of early National Baseball Hall of Fame inductees appear in this set.
