A rare original proof of Harry Potter and the Philosopher's Stone will go under the hammer at an auction in Dallas next month.

The book is an uncorrected proof from the first time the famous wizard ever appeared in print and includes various mistakes, including misspelling JK Rowling's name on the title page.

It was re-discovered in a Minster Lovell school last year after sitting in its library since 1997.
