Issued in 1966 by the Republic of Dahomey (now Benin), this attractive airmail pair commemorates the 20th anniversary of UNESCO (1946–1966). The 30F value features a stylized globe with Africa highlighted and dynamic geometric elements symbolizing global cooperation and cultural exchange. The 100F stamp presents educational and scientific motifs within a circular design, reflecting UNESCO’s mission in literacy, research, and international unity. Both stamps display the UNESCO emblem prominently and are marked Poste Aérienne, enhancing their thematic appeal. Printed in striking blue, brown, and red combinations, this set is ideal for collectors of UNESCO, Africa, education, and international organizations themes.
