Issued in 1974, this striking four-stamp set from Peru commemorates the 150th anniversary of the Battles of Junín and Ayacucho (1824–1974), decisive moments that secured South America’s independence from Spanish colonial rule. The designs, after paintings by Félix Yáñez, vividly depict scenes from the cavalry charge at Junín and the climactic victory at Ayacucho amidst the Andean highlands. Printed by Sanmartí, Peru, the denominations (S/.2.50, S/.3.00, S/.6.00 Aéreo, and S/.1.50) include both standard and airmail issues, uniting artistry and history in a powerful philatelic tribute to Peruvian patriotism.
