Three-sided (about 1.5" long on each side) piece of translucent plastic with light purple coloration holds on one corner 4 links leading to a larger ring which can be opened to hold keys. At the center of the plastic on the front is a slightly raised clear plastic dome covering an illustration with close-up of Lindy in the foreground with the nose and wing of his plane in the bkg. The reverse side of this paper insert reads "Bon Bon Sans Colorant/Caramels/Deve," this last word apparently being the company name. Tiniest traces of wear on the plastic edges barely showing. Exc. condition, the first we've seen, almost certainly from the 1927 era.
