Issued as the 3" x 3-3/4" wax wrapper for a five-cent piece of bubblegum, this "test" issue was bought up in great quantities by speculators and remains rather common. It is also inexpensive, because the comic-style paper representations were not popular with collectors. The set is complete at 33 pieces. Each wax box contains only 11 different players. - Standard Catalog of Baseball Cards, 15th Edition.
