This 1950 Mexico postage stamp (20 centavos) commemorates the opening of the Carretera Internacional highway, a major infrastructural link connecting Ciudad Juárez with Ocotal. Printed in a rich blue tone, the design features a sweeping road curve, a directional sign marked “1950,” and a transport truck symbolizing progress and modern connectivity. Issued by Correos México, it highlights post-war national development through improved internal and cross-border transportation. A desirable mid-20th-century Mexican commemorative, especially valued for its crisp line engraving and thematic appeal to transport and engineering collectors.
