Issued by Niger in 1960, this 25 Franc stamp commemorates the 10th Anniversary of the Commission de Coopération Technique en Afrique au Sud du Sahara (CCTA). The design features a globe centered on Africa, surrounded by cogwheels symbolizing technical progress and cooperation. The inscription “1950–1960 Tananarive XV Session” marks the 15th session held in Madagascar. Printed in a rich brown tone, the stamp reflects the early post-independence era of African unity and development initiatives. A meaningful addition for collectors of African history, international organizations, and thematic “cooperation” issues.
