Exhibit Supply Co. Countertop Pinball Game. Chicago: Exhibit Supply Co., ca. 1920s-1930s. Pre-flipper wooden case with a window over game area, two decals. When a penny is inserted and the lever is pulled, small balls are released into the plunger area, where one can play balls one at a time. With lock and key for wooden case. Some wear, chipping to decals. Pinball mechanism works, but reloading function requires adjustment. Good.
