Original 1941 Captain Midnight Decoder Badge, offered as a radio premium from Ovaltine during the golden age of radio. This is the "Mystery Dial Code-O-Graph" version, issued exclusively to members of the Secret Squadron. Made of stamped brass with a movable cipher wheel and pin-back design, it let kids decode secret messages broadcast during the Captain Midnight radio show. This piece is in original vintage condition with light wear from age. A fantastic example of World War II-era radio premium memorabilia and a must-have for collectors of advertising, pop culture, or early superhero and spy ephemera.
