This is a classic Superman ring that has long been gone as there were only 100 of these particular rings that were made to celebrate the 50th Anniversary back in 1988. One sold at last year's Annual Superman celebration for $125.00!!! And many have sold online for $60-$70.00 each consistently.
Classic Superman artwork by Neal Adams. This ring has never been worn or displayed as it was found in a drawer years ago at the Metropolis chamber of commerce when they moved out of their old building.
