This 0.50 guaraní commemorative stamp from Paraguay showcases Albrecht Dürer’s 1499 Portrait of Oswolt Krel, a celebrated Renaissance masterpiece held in Munich’s Alte Pinakothek. Issued as part of the “Obras Mundiales de la Vieja Pinacoteca München” (Masterpieces of the Old Pinakothek) series, it also honors the centenary of Paraguay’s Epopeya Nacional (1864–1870), the War of the Triple Alliance. The design juxtaposes European art heritage with Paraguay’s national remembrance, symbolizing the country’s cultural and historical identity through international art.
