This 5 avos commemorative stamp from Macau, then a Portuguese territory, was issued in 1970 to mark the centenary of the birth of Marshal António Óscar de Fragoso Carmona (1870–1951), who served as President of Portugal from 1926 to 1951. The design features a detailed portrait of Carmona in military uniform, flanked by coats of arms and inscribed “Centenário do Nascimento do Marechal A. Óscar Carmona 1870–1970.” Printed by Lito Nacional, Porto, Portugal, this issue reflects Portugal’s colonial-era philatelic style, characterized by fine engraving and patriotic commemoration.
