January 2017, a series of letters that Diana and other members of the royal family had written to a Buckingham Palace steward were sold as a part of a collection titled "the private letters between a trusted butler and the royal family". The six letters that were written by Diana included information about her young sons' daily life and raised £15,100. Another collection of 40 letters written by Diana between 1990 and 1997 were sold for £67,900 at an auction in 2021. In 2023, two of Diana's friends put 32 highly personal letters and cards written by her while she was going through her divorce up for auction, announcing that proceeds of the sale would be donated to charities associated with them or Diana. "Diana: Her Fashion Story", an exhibition of gowns and suits worn by Diana, was announced to be opened at Kensington Palace in February 2017 as a tribute to mark her 20th death anniversary, with her favourite dresses created by numerous fashion designers, including Catherine Walker and Victor Edelstein, being displayed. The exhibition opened on 24 February displaying a collection of 25 dresses, and was set to remain open until 2018. Other tributes planned for the anniversary included exhibitions at Althorp hosted by Diana's brother, Earl Spencer, a series of commemorating events organised by the Diana Award, as well as restyling Kensington Gardens and creating a new section called "The White Garden" in order to symbolise Diana's life and style. On 31 August 2019, the Princess Diana 3D Virtual Museum was launched to mark the 22nd anniversary of Diana's death. Operated by the Princess & the Platypus Foundation, the online museum consisted of over 1,000 of Diana's items which were photographed using the techniques of virtual reality. Legacy Public image Diana remains one of the most popular members of the royal family throughout history, and she continues to influence the younger generations of royals. She was a major presence on the world stage from her engagement to Prince Charles in 1981 until her death in 1997, and was often described as the "world's most photographed woman". She was noted for her compassion, style, charisma, and high-profile charity work, as well as her ill-fated marriage. Diana's former private secretary Patrick Jephson described her as an organised and hardworking person, and pointed out Charles was not able to "reconcile with his wife's extraordinary popularity", a viewpoint supported by biographer
