Okido: What's Inside?

This book gives children the power of X-ray vision to see what's inside things. When a child holds a page up to the light, s/he can see through to the page behind: for example, when a child holds up a page showing a car, she can see the engine under the bonnet (printed on the reverse). The book is divided into five sections: What's inside your body?; What's inside machines?; What's inside the world of nature?; What's inside buildings?; and Your turn!, in which children draw their own pictures, putting a present inside the box, snacks inside the fridge, a person behind the door, birds in the tree, etc.
