Captain Midnight Decoder Badge. The Captain Midnight decoder badge, officially called a Code-O-Graph, was a famous radio premium given to children in the 1930s through 1950s. Sponsored by Ovaltine, members of the "Secret Squadron" used the pin-back badges with rotating wheels to decode secret numeric messages broadcast at the end of each radio episode. Great collectable. Great gift for the collector. Rare. See photos for condition.
