1939 Captain Midnight Radio Premium: Flight Wings Badge

 Captain Midnight was one of many heroic pilot characters populating children's radio shows and movie serials in the 1930s and '40s. He successfully made the transition to television as well, where he had his own show presented by Ovaltine. In 1939, the Captain's radio broadcasts were sponsored by the Skelly Oil Company, who endorsed this  premium, the Mysto-Magic Weather Forecasting Flight Wings Badge.

Originally a piece of litmus paper inserted behind the "S" would change color according to varying weather conditions, alerting its young wearer to impending trouble.
