This historic 5 centavos green stamp from the Philippine Islands was issued during the Japanese occupation of World War II. Originally a U.S. Administration issue, it bears a bold black Japanese overprint dated 12-8-1942, commemorating the first anniversary of Japan’s entry into the war. The overprint, written in Japanese Katakana, references the Greater East Asia War. These stamps were created by overprinting existing Philippine stock, making them important wartime provisionals. A striking collectible that highlights a turbulent era in Philippine postal history, highly sought after by both occupation and WWII philately specialists.
