This is a novelty book project for Caterpillar Books. Each of the four books tells the
story of the machines and the drivers and how they intereact on a day at work.
The books have moving parts and also pop out parts to create a play scene.
The mini machines have proven very popular all around the world. Caterpillar have
republished the books as a box set and even a playmat with the machines modelled in wood.
