On June 24, 1997 Canada issued this stamp (Sc #1649) to commemorate the 500th anniversary of Giovanni Caboto's voyage to North America. Caboto's ship Matthew
is portrayed on the right of the stamp.
From wikipedia, "John Cabot (Giovanni Caboto) was an Italian navigator and explorer. His 1497 voyage to the coast of North America under the commission of Henry VII of England is the earliest known European exploration of coastal North America since the Norse visits to Vinland in the 11th century."
