Issued in 1975 to commemorate the 100th anniversary of the Mexico City Chamber of Commerce (1874–1974), this 80-centavo stamp features vibrant imagery drawn from the Codex Florentino, one of the most important manuscripts documenting Aztec culture. The design shows pre-Hispanic trade items, jewelry, and symbolic figures, celebrating Mexico’s indigenous commercial heritage. Printed by T.I.E.V., it blends cultural authenticity with modern Mexican philately. A sought-after thematic item for collectors of Latin America, indigenous art, or historical commerce.
