This 80-centavos airmail stamp from Mexico, issued in 1974, honors Felipe Carrillo Puerto (1874–1924), a prominent Mexican revolutionary leader and governor of Yucatán. Known as the “Apostle of the Mayas,” Carrillo Puerto championed social reform, indigenous rights, and education during the post-revolutionary period. The sepia portrait by S. Pruneda conveys both dignity and idealism, commemorating the 100th anniversary of his birth and 50 years since his assassination. The green “AÉREO MÉXICO” inscription underscores its use for airmail service.
