1947 premium from General Mills with adjustable brass bands depicting smoking lamp on each side over-printed by initials "GH." Ring top is a circular disk of glow-in-the-dark material with a small pin on top edge to hold the embossed brass cover that can swivel to the side so interior of compartment serves as secret hiding place. The brass top has large detailed hornet image and surrounding text "The Green Hornet." Compartment glows in the dark. Lower bands without luster but top two-thirds has beautiful N. Mint luster displaying essentially Mint. A choice example.
