As promised, here are some images of the real King George VI and Queen Elizabeth (yes, that is the Queen Mother who passed away in 2002, mother of our current Queen Elizabeth II). There are some photos of them in the 1920s, before Edward abdicated and George was forced to take the throne (at that time they were called the Duke & Duchess of York), through to photos of them in war-ravaged London in the early 1940s. I believe the latest photo is 1951 (she is wearing a ballgown, crown and white furs).
The LIFE photograph is of a very young Elizabeth Bowes-Lyon, before she married George (she was Scottish nobility). In another photo you might notice Eleanor Roosevelt standing between King George VI and Queen Elizabeth – this was during an inspection of English war conditions in 1942. The photo of the King & Queen, with two young princesses, waving on the balustrade, is VE Day (8 May 1945), announcing and celebrating the end of the war. On the left that is Princess Elizabeth (now our Queen), in military uniform.
