This Chilean commemorative stamp, issued in 1971, celebrates the 10th Anniversary of the Antarctic Treaty (1961–1971). The design features a sled team led by an explorer, symbolizing Chile’s scientific and territorial presence in Antarctica. Above the scene, a map of the Antarctic continent is shown with polar grid lines, emphasizing global cooperation and peace in the region.

The stamp, printed by Casa de Moneda de Chile, has a face value of Eº 3.50 and is rendered in turquoise and black tones, giving it a crisp polar aesthetic. The Antarctic Treaty established Antarctica as a zone devoted to peace and science—an important milestone in international diplomacy and environmental protection.
