Ring is from 1941, produced by Ostby & Barton of Rhode Island, offered as a premium for the “Superman Defense Club” milk program, costing 2 bottlecaps and 10¢. Hake’s Pop Culture Memorabilia 2008 Price Guide reports only 10 known: 4-Good, 5-Fine, 1-VF. In comparison, the related ring from the same promotion with a letter and eyeball on top has 27 reported known. This Superman on ring top version has sides showing a star and planet. Snap-off brass top has letter “S,” diagonal lightning bolt and well-struck image of Superman from waist up breaking a chain across his chest with image surrounded by accent lines. The ring bands are perfectly formed. Ring base has about 50% in clean brass tone and 50% still with original luster. The ring top retains over 90% luster and displays glossy and Mint. Overall, we grade VF and that places it among the best three known to us. The ring displays beautifully. Our last example in somewhat lesser condition exceeded $4,500.00.
