There were several portraits released, as well as a photograph of the Queen (wearing the George IV State Diadem, Coronation Necklace and Earrings, and Wedding Gift Bracelet) and Duke of Edinburgh going to the State Opening of Parliament earlier that month.
Throughout the previous year, numerous images had been taken for the Silver Anniversary by the Earl of Lichfield, which included Christmas at Windsor Castle, a Holiday on the Royal Yacht Britannia and a Holiday at Balmoral.
