This 10$00 escudo commemorative stamp was issued by Portugal in 1983 to celebrate the 75th anniversary of the Administração-Geral dos Portos de Lisboa (AGPL) — the General Administration of the Ports of Lisbon. Designed by António C. Magalhães and printed by INCM (Imprensa Nacional-Casa da Moeda), the stamp beautifully depicts Lisbon’s bustling harbor scene, featuring a tugboat bearing the AGPL flag, a cargo vessel, and a large port crane symbolizing maritime commerce and industrial progress.

A fine example of Portuguese maritime-themed philately, it highlights the vital role of the Port of Lisbon in the nation’s economic development throughout the 20th century.
