Got a really special postcard sent from The UN headquarter, New York!
This stamp is one of three sheets of 15 stamps issued on the occasion of the 65 anniversary of the United Nations.
Only the United Nations is permitted to issue postage stamps, even though it is an organization and not a country or a territory. Today the United Nations Postal Administration (UNPA) is the only postal authority that issues stamps in three different currencies: U.S. dollars, Swiss francs and euros. The stamps may be used for postage when used on mail sent from the United Nations offices in New York, Geneva or Vienna.
The headquarters of the United Nations is a distinctive complex in New York City, United States, that has served as the official headquarters of the United Nations since its completion in 1952.
The United Nations has three additional, subsidiary, regional headquarters or headquarter districts. These are located in Geneva (Switzerland), Vienna (Austria), and Nairobi (Kenya).
