Thanks to Rowling
JK Rowling's smallest ever Harry Potter book - measuring just one inch high -has sold for 11,000 pounds.
The leather-bound tome was a guide to everything Harry needed for his life at Hogwarts School of Witchcraft and Wizardry.
It was one of the prized lots in a charity auction organised by Tatler magazine.
Rowling's book, which included pictures of Harry's witch's hat, broomstick and wire-rimmed spectacles, was the third most expensive lot.
The Miniature Books Sale raised money for the 999 Club, a homeless charity in Deptford, south London.
