It was announced last week that a rare first edition copy of Harry Potter and the Philosopher's Stone, with personal annotations by J.K. Rowling, sold for over $228,000 for charity, and now new hand-drawn art by the author was released on her official site. The updated piece of news posted on JKRowling.com gives a brief summary of the English PEN book auction, and featured a new rendering of Professor Snape on the last page of chapter eight, The Potions Master.
