This commemorative stamp was jointly issued by Kenya, Uganda, and Tanzania in 1969 to mark the 5th anniversary of the African Development Bank (1964–1969). The design features a stylized tree symbolizing growth, development, and unity across the African continent. The African Development Bank emblem reinforces the theme of economic progress and regional cooperation. Issued in a 2/50 denomination, this stamp reflects the shared postal heritage of the East African Community period. Its bold graphic style and symbolic imagery make it a notable thematic piece for development, finance, and African unity collections. A meaningful collectible representing early post-independence economic aspirations in Africa.
