In New York, a watercolor that appeared on the first Harry Potter book's cover sold for £1.5 million.
It was dubbed "the most valuable Harry Potter item ever sold at auction" by auctioneer Sotheby's.
After over ten minutes of back-and-forth bidding, the buyer who wished to remain anonymous emerged victorious.
When it was last sold, in 2001, there had only been four Potter books published, and the sale price was £85,750.
The estimated price range for Thomas Taylor's photograph at Wednesday's auction was $400,000–$600,000 (£320,420–£480,630).
Taylor completed the artwork in two days after receiving a request from Bloomsbury publisher Barry Cunningham when he was just 23 years old.
He drew the image using a black Karisma pencil and utilized intense watercolors.
It features Harry and his lightning bolt scar next to the Hogwarts Express and is now recognizable to millions of people.
Taylor was one of the first people to read J.K. Rowling's draft of The Philosopher's Stone. She would go on to author the children's series Erie-On-Sea.
The first edition of the book sold for $421,000 (£327,000) at a Dallas auction in 2021 was surpassed by the £1.5 million sale.
In 2023, a dog-eared first edition of The Philosopher's Stone - which used to be a library book and was bought for 30p - sold for more than £10,000.
