A CHOICE EXAMPLE OF THE 1959 5¢ ST. LAWRENCE SEAWAY ISSUE WITH CENTER INVERTED.
The stamps, issued on June 26, 1959, coincided with the opening of the St. Lawrence Seaway by Queen Elizabeth II and President Dwight D. Eisenhower. The planning and production of the stamps to commemorate the event took almost as long as the construction of the Seaway itself with proposals coming forward in 1954 in the US and in 1956 in Canada. The first report of the discovery of the Seaway Inverts was when a young office boy from the Marlborough Hotel in Winnipeg purchased 30 stamps from a Post Office outlet in the Eaton store on August 20, 1959. It is believed that approximately 200 examples exist today.
