The 1939 Goudey R303 sets are among the most interesting of the 1930s gum issues. In addition to being noted for its popular Big League Gum baseball cards the Goudey Gum COmpany was an aggressive and innovative marketer. From the gimmicky exclusion of the Nap Lajoie card in 1933 to their Thumb Movies and Knot Hole League games of the later 1930s the company consistently invented (or borrowed) marketing ideas that were designed to sell more product.One of their more successful ventures involved the development of premiums - large-sized photos of popular ballplayers meant to be supplements to their mainstream baseball card sets.
