The Exhibit Supply Company (also known as ESCO) was the first company to sell cards that actually weren't meant as a premium to a product (such as tobacco, caramel or gum). Starting in 1921, ESCO placed vending machines in penny arcades filled with the stars of the day; this not only included baseball players, but movie stars, boxers and even pinup girls. The early cards could be purchased for a penny (years later they cost a little bit more) and were postcard size, measuring 3-3/8 inches x 5-3/8 inches. In 1948, ESCO produced a special HOF set featuring 33 Hall of Famers. The set leverages many of the past images from previous years and the cards are fairly common. PSA has graded 1200+ cards in total, for an average of 36 cards per player having been graded. Date: Country (if not USA): State: City: Provenance:
