This ring is accepted in the hobby as a Buck Rogers item c.1953 as it was issued at the time Sylvania television was a Buck Rogers licensee and they used Buck extensively to promote their Sylvania Halo Light Televisions. The ring has a large brass base with adjustable bands and the company "S" logo on each side. Top of the ring has a pair of lightning bolts surrounding high relief white plastic light bulb replica which glows brightly in the dark. The surface of the bulb is marked with their "S" logo but the black color detailing the text and logo is mostly missing from this example. Also upper right side of bulb has barely seen hairline on the plastic surface. Original luster is gone but brass surfaces are clean and glossy. Our last example in similar condition back in Auction #181 realized $495.00.
