This image is of King George VI and Queen Elizabeth in Ottawa, Canada’s capital city, on the King’s official birthday on the 19th of May, 1939.
The British monarch has celebrated an official birthday separate to their real birthday since George II began the tradition in 1748. The purpose of the different date was to ensure celebrations could be held in a warmer month, where there was a better chance of the weather being fine.
