The Doorknob Collection of Nursery Rhymes

Bright-eyed, grinning characters peep over the edge of Humpty-Dumpty's wall on the covers of this quartet of nursery rhymes. Cleverly packaged in a clear plastic case designed to hang from a doorknob, each of the four board books showcases a single verse: ``Humpty-Dumpty,'' ``Little Miss Muffet,'' ``This Little Piggy,'' ``Mary Had a Little Lamb.'' The tops of the books are die-cut in shapes that relate to the subjects, making each one easy to identify and snatch up. The colorful volumes slip easily out of their holder and are just the right size for small hands; toddlers will delight in this familiar fare sporting a new look. Ages 1-5. (Apr.)
