Discovery of Antarctica, Portugal

The stamp sheet from Portugal is from an issue that commemorates the discovery of Antarctica. The stamps on the sheet show several species of fauna that inhabit the Antarctic region, above and below the water line. Only about 10% of an iceberg rests above the surface of the water.

It took centuries to fully "find" Antarctica. Some places were even discovered multiple times and given different names due to the poor accuracy of navigational instrumentation at the time. GPS would have helped. And a way to share information, like the internet.

Thank you Pedro for this excellent cover!
