A rare uncorrected book proof of J.K. Rowling's 'Harry Potter and the Philosopher's Stone" is set to go under the hammer at Heritage Auctions in Dallas during the Historical Platinum Signature sale. This early edition, one of only 200 copies printed, features a notable misspelling "J. A Rowling" on its title page. Bidding, both in-person and online via Heritage Live, begins on July 25, offering collectors multiple avenues to vie for these coveted literary treasures."
