Issued in 1985, this 39-cent Canadian definitive stamp portrays Queen Elizabeth II in an elegant blue gown, wearing the George IV State Diadem and a sapphire necklace. Designed by Pierre Opéra and based on a photograph by Yousuf Karsh, it replaced earlier portraits in the Queen’s definitive series. The design combines traditional portraiture with a modern green background, symbolizing Canada’s continued ties to the Commonwealth. Printed by the Canadian Bank Note Company, it remains a popular collectible among monarch-themed philatelists.
