Toddlers love machines and things that go, and this book gives them everything they want, from a bucket truck to a tower crane to an airplane. Every other spread has an interactive gatefold which extends the original picture to three pages, revealing something new about each situation.
The last spread diagrams each city machine, providing additional information for young readers to pore over again and again.
William Low's classically-trained artist's eye adds a new layer to this genre, and both parents and children will appreciate the beautiful illustrations, the attention to detail, and the clever situational twists revealed by lifting the flaps.
