Issued by Portugal in 1983, this 27.00 escudos commemorative stamp celebrates the 100th anniversary of the Alliance Française, founded in 1883 to promote French language and culture worldwide. Designed by Acácio Santos, the stamp features a stylized golden rooster — a national emblem of France — set against a modern abstract background in the French tricolor of blue, white, and red. The elegant script “Centenário da Alliance Française” enhances the commemorative character, while the bold “PORTUGAL” inscription grounds it in national collaboration and cultural diplomacy.
