Harper & Row, Publishers 1963. Hardcover. Second State. First Edition with "Copyright c 1963 by Maurice Sendak Printed in the United States of America All rights reserved Library of Congress catalog number: 63-21253". The only difference between this printing and the first is the margin of title on the front cover was changed to the intended wider spacing, making the bottom block narrower, as seen on all later editions. No Dust Jacket. Very Good
