Queen Mary 2 White Star service porters prepare to move a steamer trunk containing the only author-signed U.S. edition of "Harry Potter and the Half-Blood Prince" into a heavily-guarded security truck for delivery to U.S. publisher Scholastic, July 12, in New York City after the trans-Atlantic crossing aboard Cunard's Queen Mary 2. The 672-page novel could break the one-day sales record on its release 16 July 2005. Amazon already has more than 771,000 pre-orders for the sixth book in the series, and Barnes and Noble expect to sell 50,000 copies per hour. (AFP Photo/WPN/Emile Wamsteker / July 13, 2005)
