This company was likely the more notable baseball card manufacturer prior to World War II. This Massachusetts-based company produced Big League Chewing Gum, and produced baseball cards from 1933 to 1941. Almost all of the cards were more square in shape compared to modern cards, and featured colorful drawings of players instead of photographs. Its 1933 set neglected to print a Nap Lajoie card, despite it being on the checklist, and only those who wrote to the company got one, making it one of the rarest of all baseball cards. Identify this company whose 1933 set includes cards of Lou Gehrig, and Babe Ruth which are the most valuable cards to ever reach auction for those players.
