This is a cast metal Liberty signal cannon, prominently marked on the barrel “LIBERTY CANNON / APRIL 6 / 1917,” commemorating the date of the United States’ entry into World War I. The cannon features a cylindrical barrel mounted on a wheeled carriage with spoked metal wheels and articulated elevation hardware. Finished in a darkened, aged surface consistent with early 20th-century manufacture, the piece reflects patriotic commemorative production associated with wartime celebrations, parades, and ceremonial signaling rather than battlefield use. The mechanical details, including the elevation screw and axle-mounted wheels, are well-executed and retain strong visual presence. These Liberty cannons were often used for public demonstrations, bond rallies, and civic events marking America’s mobilization during World War I. Dimensions: Approximately 18 x 7 x 6 inches.
