Per People, one of the stars of the hit Netflix series, Olivia Colman, donated to an online auction sponsored by one of Duchess Kate‘s charities that helps families and children in hospices. For the auction, Colman—who portrays Queen Elizabeth II in Seasons 3 and 4 of the show—offered a signed script of the Season 4 finale episode. Coleman’s signature is written across the front page of the script, which also marks her final episode appearing as the queen in the hit drama.

“The care and the nurture that you provide children and families in the most unimaginable circumstances is just awe inspiring,” the duchess wrote in a letter to the charity at the time of her visit. “I’d also like to pay tribute to all those families out there who are caring for and looking after a child with a life limiting illness. You do the most extraordinary job and I know it’s particularly hard at the moment so my thoughts go out to you all.”
