Though this image is subject to copyright, I feel its use is covered by the U.S. fair use laws because:
 * 1) It is a low resolution copy of a book cover.
 * 2) It does not limit the copyright owner's rights to sell the book in any way.
 * 3) Copies could not be used to make illegal copies of the book artwork on another book.
