First edition, first printing, first issue. Criticized at the time of publication for its dark elements, Where the Wild Things Are was soon acclaimed as a triumph of children's storytelling and book design.
It has remained a classic of 20th-century children's literature and was adapted into a film in 2009. There were multiple issues of the first edition, but this copy is the earliest, distinguished by the Library of Congress number 63-21253 on the title page, the codes 40-80 and 1163 on the front flap, and the absence on the rear flap of the mention of the Caldecott Award bestowed upon the book on publication (the winning of such a prestigious prize compelled the publishers to recall the entire edition and change the text on the dust jacket to include the achievement).
Oblong quarto. Original cloth-backed pictorial paper boards, front cover lettered in black. With dust jacket. Colour illustrations throughout by Maurice Sendak. Bookplate to front pastedown. Extremities a little bumped, some slight toning to covers, some very mild foxing; extremities of jacket slightly worn with occasional short tears, unclipped jacket a little toned: a very good copy in like jacket. Hanrahan A58; Grolier Children's 100, 97.
