In one of the palace's state rooms, curators have carefully recreated a desk the princess worked at in her sitting room at Kensington Palace, complete with family photos, cherished items and music cassettes. There's also a case of cassette tapes and a radio reflecting her love of music, along with her ballet shoes, which hung on the door of her sitting room at Kensington Palace. The tribute to Diana is part of Buckingham Palace's annual summer opening, which also includes the exhibit "Royal Gifts," a special display of over 200 gifts presented to Queen Elizabeth II during her 65-year reign. Some items were presented to the queen during state visits and overseas tours, such as a model of a warrior presented in 1974 from Papua New Guinea, and a portrait of the queen made with woven banana leaves, given to her in Rwanda in 2006.
