<p>Toddlers love machines and things that go, and this book gives them everything they want, from a cement mixer to a helicopter to a backhoe. Six interactive gatefolds extend the original pictures to three pages, revealing something new about each situation. The final double gatefold opens into a very long train and shows all the machines at work! </p><p>The last spread provides additional information about each machine for young readers to pore over again and again. </p><p>William Low's classically trained artist's eye adds a new layer to this genre -- both parents and children will appreciate the beautiful illustrations, the attention to detail, and the clever situational twists revealed by lifting the flaps.</p>
