This stamp, recognizing the 25th anniversary of the opening of the St. Lawrence Seaway, was designed by the Canadian artist, Ernst Barenscher of Kings City, Ontario. It graphically depicts an aerial view of the overall route of the seaway. The United States and Canada completed the St. Lawrence Seaway in 1959. The 2,342-mile waterway, together with the Great Lakes, allowed for 9,500 miles of continuous water navigation - stretching from the Atlantic Ocean to Duluth, MN - and opened the industrial and agricultural heartland of North America to deep-draft ocean vessels. Just a wonderful poster from the US Postal Service. Thanks so much for checking out our Shop.
