Prince Charles has recently celebrated the 40th anniversary of his foundation The Prince’s Trust with a star-studded garden party at the Buckingham Palace. The future king of Britain has also received special and unique gifts to mark the occasion.

London’s Buckingham Palace was filled with a mix of British celebrities, volunteers and supporters of Prince Charles’ The Prince’s Trust who attended the foundation’s anniversary celebration on Tuesday evening. During the event, the royal prince was given two special gifts, Hello magazine reported. The first was a portrait of Prince Charles presented by Joan Collins while the second was a bronze bust of the royal prince.

Collins presented the portrait as a special 40th anniversary memento from The Prince’s Trust. The actress stated that it was her “privilege to be able to present” the portrait to Prince Charles, as indicated in the same report. "His innovation not only saw the creation of the charity 40 years ago but continues to drive the work it does today,” she added.

The portrait is also a unique picture of the royal prince. The black-and-white artwork was a collage of several pictures of The Prince’s Trusts fundraisers, volunteers, supporters and beneficiaries. The picture was created by Welsh artist Nathan Wyburn, according to Express.

Meanwhile, the bronze bust of Prince Charles presented to the royal prince during the event was created by Frances Segelman. The life-like bust reportedly took several years to complete. It will be placed at The Prince’s Trust’s London headquarters.

Other celebrity ambassadors, who attended the Buckingham Palace garden party, included Ben Kingsley, Fearne Cotton, Gemma Arterton, singer Pixie Lott and former “James Bond” actor Roger Moore. Lott has been an ambassador for The Prince’s Trust since she was 18 years old while Kingsley has been a part of the foundation for 20 years.

Prince Charles established The Prince’s Trust in 1976 to help Britain’s young people.
