Illustrations are such a large part of picture books, that I often wonder why so many reviewers fail to mention the illustrator. They are responsible for a great deal of the interpretation of the author's vision. Illustrations add great depth to the overall story. Some of the finest picture books are almost or entirely wordless.
A satisfying picture book opened in the lap of a child or adult is like a mini art gallery.
The reader can visit places only imagined ... and do so over and over again.
