Guam Flag and Seal
Prior to 1917, the colonial flags of Spain and later the United States were singularly flown over Guam from 1565 until 1917 when the Guam seal and flag were accepted by the Naval government, which formally adopted them in 1930. Following the enactment of the 1950 Organic Act of Guam by the U.S. Congress, the Guam Congress passed Public Order No. 33 designating the 1917 design as the official territorial seal, which was approved by the military postwar Governor, Admiral Pownall.
The Lieutenant Governor of Guam is the official keeper of the seal. The Guam Flag, bearing the Official Seal, is recognized and flown throughout the world and at the United Nations and the U.S. Capital as our national symbol.
