The St. Lawrence Seaway provided for passage from the Atlantic Ocean to the Great Lakes. It was a collaboration between the United States and Canada. The Seaway was opened in 1959 with a ceremony led by Queen Elizabeth II and President Eisenhower. Both the United States and Canada issued stamps to commemorate the event. Both stamps have the same basic design, except the Canada stamp has bilingual text at top. The invert is only known on the Canadian stamp.
Charles J. G. Verge provides a census of multiples in his book on the Seaway Issues. Only three multiples larger than a block of four are available to collectors. The block offered here was part of a block of six illustrated in an issue of The Canadian Philatelist. The lower pair was removed prior to 1982. This is also one of only two recorded blocks of four from the top right corner of the sheet.
