*1*Sports Illustrated has called Ethan Allen, "The Father of Baseball Board Games." As recounted in a 1991 SI article, "Allen dreamed up All-Star Baseball toward the end of his playing days. He peddled his spinning wheel of fortune all over toyland. Everyone passed. Finally, he got an audience with Don Mazer, the president of Cadaco, a Chicago-based toy-maker. Mazer pounded a fist on his desk. 'That's an idea!' he said. 'Let's do it.'" Here, the great Grover Cleveland Alexander consents to the usage of his name and stats in the 1941 board game, which would go on to become not only one of the best-selling baseball games in history, but also one of the most influential board games period. The 6x6 onionskin-like sheet features Allen's name typed at top left, with Alexander's "8-9" strength signature and handwritten address below the contractual text. Light folds and creases throughout.
