A clean mid-century architectural rendering of the iconic UN Headquarters complex in New York, prominently featuring the tall Secretariat Building alongside the General Assembly Hall. The bold blue-green palette and modernist lines reflect the optimism and internationalism of the post-war era. The UN emblem at upper left reinforces the theme of global cooperation and diplomacy. Issued as a low denomination 6¢ value, it was widely used on everyday UN correspondence, making fine centered examples desirable. A classic topical choice for collectors of architecture, international organizations, and peace themes.
