Issued by the United Nations (New York) in 1957, this commemorative stamp set honors the establishment of the United Nations Emergency Force (UNEF), one of the world’s first international peacekeeping missions. Featuring the official UN emblem within a symbolic circular design, the stamps represent global cooperation for peace and conflict resolution following the Suez Crisis. The multilingual inscriptions emphasize international unity and diplomatic responsibility. These early UN peacekeeping issues are highly valued by thematic collectors focusing on peace, diplomacy, and international organizations. A classic mid-century United Nations philatelic issue ideal for UN or political history collections.
