This historic airmail stamp from the Philippines features a green vignette of a native sailboat and airplane, originally issued under U.S. administration. During the Japanese Occupation in World War II, it was overprinted with “REPÚBLIKA NG PILIPINAS” and dated 5-7-44, symbolizing the wartime puppet republic. The original 60c denomination was surcharged to 12 centavos, creating a striking dual-value appearance. Such overprints mark a turbulent chapter of Philippine history, making them prized by specialists of wartime issues. A true collectible that captures both aviation and WWII postal heritage.
