A letter from Princess Diana with the scrawled signatures from young Princes William and Harry has emerged for sale for £18,000.
The handwritten note from the Princess was to thank a police sergeant for putting on a motorbike display for William’s birthday party.
The boys, then aged seven and four, added their names to the bottom –
William’s in joined-up writing and Harry’s with larger, separated letters.
Sgt George Plumb of the Metropolitan Police and the Special Escort Group put on the dazzling display for William, Harry and their friends on the grounds of Kensington Palace in 1989.
Diana’s letter is dated June 21, 1989 and written on Kensington Palace headed paper.
It reads: “Dear Sgt Plumb, It was so very kind of you and your team to have come here today on William’s birthday – I cannot begin to tell you what pleasure the display gave to all those little people and their mothers!
“I know how particularly busy you all are at the moment, so it meant even more to us that you and the motorbike boys were able to take part in the birthday celebrations!
“This comes with our warmest possible thanks. Yours sincerely Diana, William, Harry.”
