Scholastic unveiled the new cover by cartoonist Kazu Kibuishi for the sixth book in J.K. Rowling's Harry Potter series, The Half-Blood Prince, during a party held last night at Comic-Con International in San Diego.

Announced in February, the new covers by the acclaimed creator of Copper, Daisy Kutter and Amulet were commissioned to commemorate the 15th anniversary of the U.S. debut of Rowling's beloved fantasy series. The art for the seventh and final novel, Harry Potter and the Deathly Hallows, will premiere July 31 at a birthday party for the books.

The new editions will be available beginning Aug. 27, with a boxed set scheduled for release in September.
