Amazing Pop-Up Big Machines

The movers and shakers in this colorful pop-up include a tractor, forklift, and tower crane. Side panels open to reveal photographs of machines in action and additional information about how they operate. Readers can manipulate moving parts on the pop-ups: via pull-tab, a bulldozer's blade scoots forward, and paper objects contained in a side pocket (boulders, planks) can be loaded into the back of a dump truck. Some of the interactive effects fall a little short—attaching paper tools and trailers to the back of a tractor may be difficult for little fingers—but truck and other rig enthusiasts should be captivated. Ages 4–up. (Nov.)
