It is not an exaggeration to say that this is one amazing pop-up book. Each page has a working machine that becomes a play setting with moving parts. The text folds out and tells what the machine does. It's hard to say which of these is the mast awesome—the dump truck, bulldozer, tractor, forklift or tower crane. There are extra play pieces in pockets and even directions for making each machine work. They say 4 & up, but we’d say you will need to supervise the way this is handled to avoid tears over broken machines. This is a work of paper engineering art!
