Peggy Rathmann's- Goodnight Gorilla

  In this limited-word picture book, a gorilla follows the zookeeper as he says good-night to his charges. What the zookeeper doesn't know is that the mischievous gorilla has snatched his keys and is letting out the animals almost as fast as the zookeeper can lock them up. The animals follow him to his house and into the bedroom, where, in an amusing pitch-black spread, a pair of worried wide-open eyes let the zookeeper's wife know that she and her husband are not alone. Jaunty four-color artwork carries the story and offers more with every look.
