Maurice Sendak did this poster for The Horn Book Magazine, the venerable review of books for young readers. Its current editors, Roger Sutton and Martha Parravano, put together A Family of Readers: The Book Lover's Guide to Children's and Young Adult Literature (which we highly recommend). Below is another great Sendak poster, with which we bid a wistful farewell to summer.
Sendak illustrated many books by other writers, as well as his own. These beautiful images come from The Moon Jumpers by Janice May Udry. Get your copy while they last!
