Canada Post Corporation continues its tradition of featuring the Canadian Flag on postage stamp with a 42-cent definitive stamp issued on December 27, 1991. A one-colour steel engraving of the Flag appears on the 42-cent roll of 100 stamps. Toronto designers Gottschalk + Ash International were responsible for all of the Flag stamp designs, including the 42-cent "Quick Sticks" self-adhesive Flag stamp. The Maple Leaf Flag appeared on a Canadian stamp in 1965, to mark its official proclamation on February 15 that year.
