This 40 centavos Mexican postage stamp, issued in 1974, honors Mariano Azuela (1873–1952), one of Mexico’s most significant literary figures. Azuela, a physician and novelist, is best known for Los de Abajo (The Underdogs), the seminal novel of the Mexican Revolution that vividly portrayed the struggles and disillusionment of its fighters. The stamp, designed by H. Rodríguez and printed by T.I.E.V., features a finely detailed portrait of Azuela in formal attire, rendered with subtle color shading. The clean, minimalist design emphasizes his stern expression, reflecting his realism and deep insight into Mexico’s revolutionary era.
