Issued by Mozambique in 1969, this commemorative stamp honors the centenary of the birth of Portuguese aviation pioneer Admiral Gago Coutinho (1869–1969). The design features a portrait of Coutinho alongside an illustration of Aeroporto Almirante Gago Coutinho, symbolizing his legacy in navigation and aviation history. Printed in multicolor with detailed architectural artwork, the stamp reflects the colonial-era postal themes linking aviation achievement with infrastructure development. Collectors value this issue for its historical aviation connection and attractive mid-20th-century Portuguese colonial design. Well-centered examples with clean perforations are especially desirable in thematic aviation collections.
