Issued by New Zealand in 1971, this striking 6-cent commemorative stamp marks the 10th Anniversary of the Antarctic Treaty, which came into force in 1961 to ensure peaceful scientific cooperation on the continent. The design features a stylized polar projection of Antarctica encircled by intersecting ribbons of green, blue, and violet, symbolizing unity and collaboration among nations. The vivid modernist artwork reflects New Zealand’s key role as a gateway to the southern polar region and a signatory to the Treaty. A classic issue for collectors interested in polar exploration, diplomacy, and environmental preservation.
