Harry Potter world record up 775% at Sotheby's auction

A first edition copy of Harry Potter and the Philosopher's Stone, annotated and illustrated by author JK Rowling, has set a new auction record at Sotheby's First Editions, Second Thoughts auction.

The book sold for an impressive £150,000 ($227,993) in London last night (May 21), destroying the previous $26,046 world record for one of the 500 first editions from 1997 by 775.4%.

The previous record was set only in April 2013, displaying the continuing popularity of Rowling's landmark children's book.

Kazuo Ishiguro's Remains of the Day, illustrated and annotated by the author on 51 of its pages, brought the third highest bids of the auction, selling for £17,000 ($27,359). The price represents a 125% increase on its £8,000 high estimate.
