This is my great-grandfather’s security badge from the early 1940’s. He worked at the Jubilee Manufacturing Company, which was apparently a defense contractor in Omaha, Nebraska. The badge consists of a round piece of metal with a “safety pin” fastener on the back. The image is considerably larger than the actual badge, which only measures about 1-5/8 inches (4.1 cm) in diameter. The original scan can be accessed through the link below:
