Harry Potter Sketches

Two preparatory sketches by Cliff Wright for the cover of Harry Potter and the Prisoner of Azkaban are to go on sale at the 14th annual Glasgow Art Fair. On the left is a sketch of Harry and Hermione riding a Hippogriff; on the right The Grim, a dog-like omen of doom. They are expected to sell for £13,000 and £11,000 respectively. So don't all rush at once.
