This powerful 1968 Argentinian commemorative stamp honors the 150th anniversary of the Battle of Maipú, a decisive victory in the South American wars of independence led by General José de San Martín. Rendered in deep blue engraving, the design shows cavalry and infantry in dynamic motion, with banners raised high in celebration of liberation. Issued by the Casa de Moneda de la Nación, this 40-Pesos stamp is prized for its detailed historical artwork and classic engraving style by Giorgio Nicastro. A fine addition for collectors of Latin American history, independence movements, or military-themed philately.
