The Big Book of Big Machines

Exciting fold-out panoramas show machinery at work. Single panels isolate the same machines with easy-to-understand definitions (“An excavator digs big holes in the ground.”) and captivating facts (“Maximum digging depth: 16 feet — the same as the height of a giraffe.”) Organized by work environment (farm, building site, dock, etc.); this is a detailed resource children will love. Hardcover; large format, 28 thick pages.
