Do you like pop-up books? Maurice Sendak and Matthew Reinhart worked together to create a hillarious pop-up book titled "MOMMY?" about a little boy that wanders into a house filled with a vampire, a mad scientist, a mummy and more. Robert Sabuda has a fun website with pop-up activities and a sneak peek of this pop-up book. To check it out click on the "pop-up books" link.
