A beautifully engraved 1973 commemorative from France, issued for the 50th Anniversary of the Académie des Sciences d’Outre-Mer. The design features a stylized world map in red within a globe framework, symbolizing global knowledge and exchange. Below it appears the academy’s motto — Aimer, Comprendre, Savoir, Respecter — elegantly woven into an abstract emblem. Printed by J. Combet, this 1.00 franc issue appeals strongly to collectors of French intellectual history, scientific institutions, and thematic world-map philately. A refined and visually rich commemorative from the classic engraved era of French stamps.
