FILE - Britain's Queen Elizabeth II, then Princess Elizabeth, centre, waves as she stands on the balcony of Buckingham Palace, London, with her grandparents King George V and Queen Mary, in this May 6, 1935 photo. Princess Margaret is just visible over the balcony edge. The balcony appearance is the centerpiece of almost all royal celebrations in Britain, a chance for the public to catch a glimpse of the family assembled for a grand photo to mark weddings, coronations and jubilees.
