Issued by the United States in 2000, this commemorative miniature sheet honors the 55th Anniversary of the United Nations. It features two striking stamps: a 33¢ value showing the installation of the UN emblem, and a 55¢ value depicting the construction of the iconic UN Headquarters in New York. Designed in a blue-tinted style with historic photographs, the sheet captures the spirit of international cooperation and post-war rebuilding. A must-have item for collectors interested in United Nations history, U.S. commemoratives, and millennium-era philately. This sheet stands as a symbolic tribute to peace and diplomacy at the dawn of the 21st century.
