From the Daisy Airgun Museum Website:
"In 1940, Daisy manufactured the Superman Krypto-Raygun toy. The toy was a miniature projector that projected inserted filmstrip images on a wall or anything that it was pointed at. This raygun is reputed to be made of Kryptonite, an amazing, unknown metal found only on the distant Planet Krypton, Superman’s birth-place.
Unfortunately, the raygun was short-lived with Daisy’s efforts being directed to the war effort one year later.”
