The stamp pictures a Viking ship, a map of the Atlantic with the presumed route of Leifr Eriksson to the North American continent in 1002 and 1008. Leifr and his brother Thorvald who accompanied him were the sons of Eric the Red of Norway who settled Iceland about 978-982, and then went on to Greenland in 985.
     The stamp was issued April 30, 1934 to mark the New York World's Fair in 1939. It was overprinted 1940 on April 30, 1940.
