A striking mid-century Mexican commemorative depicting the massive concrete viaduct of the International Highway linking Ciudad Juárez to Ocotal, symbolizing national infrastructure growth and cross-border connectivity. Printed in a rich violet-purple intaglio style, the strong architectural lines and deep shadows give the bridge impressive depth and realism. Issued by Correos México in 1950, this stamp belongs to Mexico’s popular “public works and modernization” thematic issues. The wide horizontal format and bold “15c” numeral make it visually distinctive in albums. A desirable piece for collectors of transportation, engineering, and Latin American development themes.
