SHEPARDSON BOOKSTALL, 20 YEARS OF EXCELLENCE. First Edition book identified by the title page (See Scan); the book is in fine condition with clean pages and bright color. DJ is a later issue covered in mylar to protect; has a gold Caldcott Medal on front; clipped on the front inside flap bottom corner, with $3.50 price on top corner. I have personally checked this out with Sendak expert/author, Joyce Hanrahan (Works of Maurice Sendak) and she declared it a true first edition explaining that the Library of Congress catalog number was issued in November 1963, therefore on the first printings in 1964, but not thereafter. Because the DJ is not a first issue, I have priced it accordingly. Still the best children's book every written and illustrations are stunning.
