This 50 centavos Correo Aéreo stamp from Mexico, issued in 1959, commemorates the centenary of the birth of President Venustiano Carranza (1859–1920). Carranza was a key leader in the Mexican Revolution and later the author of the 1917 Constitution, a foundational document for modern Mexico. The stamp features his portrait on the right and the script “Plan de Guadalupe – Constitución de 1917” in elegant calligraphy, referencing his pivotal political manifesto. Printed by Talleres de Impresos de Estampillas y Valores, this issue celebrates both constitutional reform and revolutionary leadership.
