This 1956 Mexican airmail stamp commemorates the Centenario de la Estampilla — the 100th anniversary of the first Mexican postage stamp (1856–1956). The design features José María Morelos, one of Mexico’s most revered independence heroes, shown with his characteristic headscarf. Behind him, a dynamic wartime scene depicts a cannon and a soldier, symbolizing the nation’s heroic struggle for freedom, inscribed México Heroico.

Printed by Talleres de Impresión de Estampillas y Valores de México, the stamp bears a 50¢ airmail denomination (Correo Aéreo) and was part of a broader issue honoring Mexico’s postal history. Its deep violet tone and strong patriotic imagery make it a notable piece for both airmail and historical-theme collectors.
