Brazil's First Expedition ~ 1982-1983

     Brazil made its first Antarctic expedition in 1982-83. The stamp shows an Adeliea Penguin, a small polar projection of the Antarctic continent, and the support ship, Barão de Teffe. The Barão was built in 1957 and was used by the French Antarctic Territories for 18 years under the name Thala Dan. It was sold to Brazil in 1982.
     Brazil owns a permanent base on King George Island, off the long finger south of South America, and has been granted a zone of interest between 28°W and 58°W, which overlaps territory claimed by Argentina, Great Britain, and Chile.
