This Library of Congress First Edition 1963 printing of Where the Wild Things Are is a Harcrest Library Edition of the book, which means it was made with a stronger binding.  All pages are intact and the cover has minimal wear.  There are two pages with some coloring marks (see pictures) and a few pages with identification marks from the New Orleans Public Library.  There is some minor rippling along the bottom of the pages.  It is in impressive condition, especially considering it was a library book.
