This 1950 Mexican airmail issue (Correo Aéreo) commemorates the Carretera Internacional, the Pan-American Highway route passing through Oaxaca, birthplace of President Benito Juárez, whose portrait appears at left in an elegant oval frame. The map design highlights the roadway’s symbolic connection to national development and Juárez’s enduring legacy as a reformist leader. Printed by Talleres de Impresión de Estampillas y Valores, the stamp is executed in green with strong engraved detail typical of mid-century Mexican airmails. A desirable thematic item for collectors of maps, statesmen, Mexican postal history, and airmail routes.
