Queen Camilla will give a stuffed toy to a library during the royal US visit to complete its collection.
Roo, a character from Winnie-the-Pooh, has been specially created by a British teddy bear maker for the New York Public Library, which will receive the gift from the Queen.
Camilla and the King are due to arrive in the US on Monday for a four-day visit, during which they will meet Donald Trump and enjoy a White House banquet as guests of honour.
Trump has said the state visit could work towards repairing the US-UK relationship, which has come under severe strain over the war in Iran.
On Camilla’s itinerary is a visit to the New York Public Library, where she will view its permanent Treasures collection.
This is home to the teddy bears that belonged to Christopher Robin, son of Winnie-the-Pooh creator A A Milne, and which are believed to have inspired the stories first published a century ago, in 1926.
The collection on display currently includes Winnie, Tigger, Piglet, Kanga and Eeyore.
It is missing the original baby kangaroo toy – Roo – which was lost in an apple orchard in the 1930s.

Queen Camilla will take the toy with her when she travels to the States on Monday, alongside King Charles, for the state visit
The Queen will give the library a Roo made specifically for the visit by traditional British teddy bear makers Merrythought, who produced the original toys at the start of the 20th century.
The design is based on the original illustrations.
The Roo toy, currently in Buckingham Palace, will join Camilla on the royal plane for the transatlantic journey.
The build-up to the visit took an unexpected turn after a gunman targeted top Washington officials at a dinner attended by the President.
Trump, who was injured in a previous assassination attempt, was swiftly evacuated by secret service agents along with other senior members of the administration.
The President said later that the culprit appeared to be a ‘lone wolf whack job’.
Ministers said on Sunday that the King’s security in America is being taken ‘very seriously’ in the light of the attack.
Keir Starmer has spoken to the US President to express his ‘shock’ and ‘relief’ he was not hurt in the disturbing episode.
‘Any attack on democratic institutions or on the freedom of the press must be condemned in the strongest possible terms,’ the PM posted on X.
‘It is a huge relief that @POTUS, the First Lady and all those attending are safe.’
In interviews this morning, Cabinet minister Darren Jones insisted ‘appropriate’ measures would be in place for the monarch’s State Visit this week.
