Convention

The Convention pinball machine, designed by Harry Mabs with art by Roy Parker, was manufactured by D. Gottlieb & Company in June 1940. It is a single-player, flipperless electro-mechanical (EM) machine with a government/politics theme, offering a glimpse into the era's amusement industry just ahead of America's entry into World War II.

As a flipperless EM game, Convention relies on levers, relays, and mechanical switches rather than player-controlled flippers, which is characteristic of pinball design before the flipper's introduction in the late 1940s. Detailed information about its specific gameplay features is scarce.

Government and politics themes were uncommon in pinball generally, and Convention's early date and subject matter make it a notable and rare find for collectors and historians of early Gottlieb machines.
