As part of the Royal Childhood exhibition opening at Buckingham Palace on Saturday, Queen Elizabeth II has allowed family home video footage to be released for public viewing – most of the stills and videos have never been seen before.
In one grainy video, Princess Elizabeth can be seen catapulting her little sister Princess Margaret in the air with glee as the pair enjoy a giggly ride on a traditional seesaw in their garden.
Another highlight is seeing the Queen Mother (the Queen at the time the film was shot in the 1930s) performing a choreographed line dance with her daughters, Princesses Elizabeth and Margaret, alongside their governess, Marion Crawford, known as “Crawfie” – the foursome laughing as they jig around energetically onboard a royal yacht.
In other scenes, the Queen (who was in her early 20s and still a princess) can be seen hiding her face behind a handkerchief, playing peekaboo with Prince Charles as a baby. Her husband, the Duke of Edinburgh, seems hands-on as a father, as he races along on a miniature bike with both Prince Charles and Princess Anne.
