20th Anniversary of UNESCO
UNESCO (the United Nations Educational, Scientific and Cultural Organization) was established in November 1946 to promote world peace and international cooperation through education, science, and cultural preservation. Following its independence, Mauritania joined the organization to advance literacy, safeguard its rich manuscript tradition in historic desert ksour (such as Chinguetti and Ouadane), and foster global educational partnerships.
Issued in November 1966 by the Islamic Republic of Mauritania (REPUBLIQUE ISLAMIQUE DE MAURITANIE / الجمهورية الإسلامية الموريتانية), this commemorative postage stamp marks the 20th Anniversary of UNESCO (1946 UNESCO 20 ANS 1966). Designed by H. Biais and printed by SO.GE.IM., the graphic layout features the official UNESCO temple emblem set inside a central oval band bordered by traditional geometric motifs and crescent moons, symbolizing international cultural collaboration.
