Queen Elizabeth II has actually been a fairly popular Queen and she is the longest service British Monarch in history. She celebrated her Diamond Jubilee in 2012 marking 60 years of reign. Call it lucky, but when the Queen was born, she wasn't slated to take over the throne at all. Her Uncle, King Edward VIII was actually in line and after a brief time as King, he abdicated the throne to his brother, King George VI, and Queen Elizabeth now had rights to the throne when her father passed away in 1952.
The main focus of this 1937 Wills's "Our King and Queen" set was on Princess Elizabeth's parents, King George VI and Queen Elizabeth I. In 1937, they had only been in reign for a year so they captured some interesting moments in the 50-card set. Princess Elizabeth is shown on three cards in this set.
Card #2 (The Royal Family) shows her with her sister and parents
Card #4 (The Royal Princesses) shows her with her sister
Card #50 (The Princesses and their Miniature House) shows her with her sister
