Princess Diana (opens in new tab) was famous for her love of sending heartfelt, handwritten notes. Now, royal fans are getting a new look at an unearthed note the late royal wrote in the late eighties, nearly a decade before her untimely death in August 1997.

The letter in question (which is being auctioned in the U.K. (opens in new tab) by auction house William George (opens in new tab)) is dated June 21, 1989, to be exact. Diana penned the note on official Kensington Palace letter-head as a thank you to Sergeant George Plumb of Scotland Yard’s elite Close Protection Group, who helped organize a special motorcycle display for her oldest son, Prince William’s (opens in new tab), 7th birthday, according to People (opens in new tab)

What makes the letter extra special are the additional signatures—from birthday boy Will and his younger brother, Prince Harry (opens in new tab), who was just five-years-old at the time.

The letter 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."
