A Ralston cereals premium, sponsor of the radio show. Gold plastic base has "TM" initials printed along the top front and reverse edges of the ring base. Ring top has clear plastic dome and interior center shows black area representing the tiger eye. With exposure to light the entire dome glows brightly in the dark except for this dark area with the resulting image representing a tiger's eye reflecting light. Essentially Mint and glows like new. Comes with original mailing box 3x4x1" deep with "Premium Library" sticker on front which we think denotes this was one in the collection of competing cereal company General Mills and sold in their 1980s archive auction. Box has one side panel crease but VF.
