Liberty

Liberty, manufactured by Bally in May 1944, is an early electro-mechanical (EM) pinball machine from the World War II era, a period when many manufacturers, including Bally, continued limited output of games amid wartime material restrictions.

As a 1944 release, Liberty predates the introduction of the pinball flipper, which debuted in October 1947 with Gottlieb's Humpty Dumpty. Gameplay therefore relied on plunging, tilting, and target-based scoring mechanisms typical of pre-flipper EM machines, rather than player-controlled flippers.

Little specific information survives about Liberty's theme, artwork, or notable features. Its minimalist design is consistent with the practical, resource-conscious manufacturing common during wartime, reflecting the era's focus on functional simplicity over elaborate visuals.
