This 1971 Mexican airmail stamp honors Mariano Matamoros (1770–1814), a key leader in Mexico’s War of Independence. The design, inspired by a mural by Diego Rivera, captures Matamoros’s determined expression, symbolizing his courage as a revolutionary priest who fought alongside José María Morelos. Issued by T.I.E.V. (Talleres de Impresión de Estampillas y Valores), the stamp features warm earthy tones characteristic of Rivera’s style. It holds strong historical and artistic appeal for collectors interested in Mexican Independence and Latin American art themes.
