Big Trucks and Diggers in 3-D [With 3D Glasses]

Big Trucks and Diggers in 3D by Mark Blum allows readers to view a ""TH103 Telescopic Handler"" (named for an extension that stretches out like a telescope) and a ""854G Wheel Dozer"" through a pair of 3D lenses built into the front-cover flap. After looking at these massive machines, children can find out how each one operates. ( May)
