A two player machine made by Williams Electronics of Chicago, IL circa 1976. The back-glass for Space Odyssey was very clearly an adaptation of Robert McCalls poster art for Stanley Kubricks film, 2001: A Space Odyssey, and speculation that a lawsuit was forthcoming prematurely halted production of these machines. In overall very good original condition with coin mechs intact, good back glass with no flaking, playfield has some wear. Plays well. Includes keys. Measures 52" long, 22" wide, 72" tall on steel legs.
