The bucket of a backhoe swoops toward you. A disk plow sweeps across fields. You can almost smell the hot asphalt being laid down by the paver in this exciting 3-D book. Stereoscopic photography has been around for more than 100 years, and it hasn't lost it's capacity to amaze both children and adults. Look through the stereoscopic glassesbuilt right into cover so they can't get lost--and view these massive building machines in all their glory.
