The Wonder Photo Cannon is a magazine camera for one-inch diameter ferrotype plates, made ca. 1910 by the Chicago Ferrotype Company.[1] As the name suggests, it is cannon-shaped, and metal-bodied.[2] The plates are held in a tube under spring pressure from behind.[3] The exposed plate at the front is released through a duct into the developing tank below the camera. There are simple viewfinder sights on the top of the camera.
