These baseball cards were included in cigarette and loose tobacco packs by the American Tobacco Company from 1909 - 1911. Prized for their rarity, diminutive size, and print quality, this particular series includes over 500 major and minor league baseball players, and is THE penultimate set for card collectors! The individual cards are archivally encapsulated and presented together in an aged black wood profile from Larson Juhl, multi opening double sided matting from Crescent Brands, and TruVue 99% UV filtering “Conservation” glass.
