SUPERMAN SECRET COMPARTMENT RING
Superman ring. Since the 1920s, many companies have included premiums in their marketing strategy as a way to boost sales. This ring is a Superman candy ring that was ordered free for 75 Superman Candy Ring coupons or for 10 coupons and 10 cents. The collector received a gold- colored, brass-finished ring emblazoned with his or her intials, complete with a secret compartment revealed when the top portion of the ring is flipped back. Superman's image is printed on paper in red and blue and is affixed to the inside of the top, insert in outstanding condition. Extremely rare.
