Ring is from 1941, produced by Ostby & Barton of Rhode Island, offered as a premium for the Superman Defense Club milk program, costing two bottlecaps and 10¢. The sixth edition Hake's Guide To Character Toys reports only 9 known; 4 Good, 4 Fine, 1 VF. In comparison, the related ring from the same promotion with a letter and eyeball on top has 27 reported known. The rarest of the two designs being offered here has top sides showing a star and planet. Snap-off brass top has letter "S," diagonal lightning bolt and extremely well-struck image of Superman from waist up breaking a chain across his chest with image surrounded by accent lines. To the casual glance, the top one-third of the ring has bright brass luster appearing Exc. Only under magnification is it obvious that some lustrous coating is gone, primarily from raised details of image area. Where the ring sides begin to narrow to form the band, the lustrous coating is gone but the band has clean metallic brass luster. Our example graded "Exc." in Auction #190 sold post-auction for $9,990. This example has Exc. luster on top one-third and Fine finish on lower two-thirds.
