Picture book for toddlers in which the younger members of a family dress up in a linen cupboard as characters such as a dinosaur and a fairy. The readers are invited to guess, from the clues in the rhyming verse, what the character is that is behind the cupboard door (which is a flap that opens in the book). Also in the 'Open-the-Door' series is 'Monsters are Knocking'. Author/illustrator's other works include 'Magic Beach' and 'My Farm'.
