Buckingham Palace, London.
King George VI, Queen Elizabeth (Queen Mother), Princess Elizabeth (later Queen Elizabeth II) and Princess Margaret appear on the balcony of Buckingham Palace. The cheers of the crowd are heard.
This is probably from June 1939 when the Royal Family returned home from touring Canada and visiting the United States.
