On today’s date in 1964, Prince Edward Island adopted its provincial flag.
Designed by Conrad Swan—the first Canadian to serve in the College of Arms—and based on the province’s coat of arms, the provincial flag was produced in anticipation of Canada’s centennial celebrations in 1967. Adopted by an act of the legislature in 1964, the flag of Prince Edward Island is bordered on the three sides away from the mast by alternating strips of red and white. The flag’s proportions are three by length and two by width.
1979 PROVINCIAL & TERRITORIAL FLAGS ISSUE
In 1979, Canada’s Post Office Department (now Canada Post) featured the provincial flags on its Provincial and Territorial Flags issue (Scott #821-832). Included in the 12-stamp issue was a stamp featuring the flag of Prince Edward Island (SC #827).
Released on Canada Day, 1979, the sheet of 17-cent stamps depicts the flags of the 12 provinces and territories that made up Canada at that time.
The following year, Newfoundland and Labrador adopted its own flag, and in 1999, the territory Nunavut was established.
According to The Unitrade Specialized Catalogue of Canadian Stamps, the stamps were designed by Raymond Bellemare and printed by Ashton-Potter using six-colour lithography. Each of the stamps is valued at 40 cents (never hinged to very fine condition) with a pane of 12 stamps valued at $5.50.
The catalogue also notes four different philatelic panes exist depending upon the position of the corner inscription. These include an upper-left pane and an upper-right pane as well as a lower-left pane and a lower-right pane (SC #832a).
