This elegant commemorative stamp from Mexico, issued in 1975, honors the 100th anniversary of the Academia Mexicana de la Lengua, founded in 1875. The design features the Academy’s emblem— a classical helmet with a plume, framed by laurel branches and the motto “Limpia, fija y da esplendor” (“It cleans, fixes, and gives splendor”). Printed in warm brown and gold tones, it reflects the institution’s cultural prestige and its role in preserving the Spanish language in Mexico. A refined and meaningful thematic item for collectors of literature, language institutions, and Mexican commemoratives.
