Issued to commemorate the 15th anniversary of the United Nations (1945–1960), this striking 150 Gourdes stamp features an engraved skyline view of the UN Headquarters in New York, paired with the official UN emblem. Printed in a classic single-color blue tone, the architectural detailing and crisp line work give it strong visual appeal for thematic collectors. The vertical “AVION” marking indicates its airmail usage. A desirable Cold War-era international relations issue, it fits well in UN, architecture, and Haiti commemorative collections. Clean examples with sharp perforations are especially attractive for exhibition pages.
