Harry Potter final book cover unveiled

We can't yet judge the book, but the publishers of the final Harry Potter adventure on Wednesday showed off the covers.

"Harry Potter and the Deathly Hallows," the seventh adventure of the boy wizard by J.K. Rowling, will be published on July 21.

The cover for the children's edition released by Bloomsbury Publishing PLC, Rowling's British publisher, shows a grown-up-looking Harry, Hermione and Ron.

The adult edition has a photograph of a locket bearing a serpentine "S" - believed to be the "horcrux" in which the Lord Voldemort keeps a fragment of his soul.

The U.S. edition will have different illustrations, Bloomsbury said.
