You ve probably seen Caterpillar (CAT) machines on a construction site, or Caterpillar tractors in a field.  But did you know there are more than 30 different kinds of CAT machines?  And each one of those machines comes in different models and sizes, from big to absolutely enormous.  This book will tell you about some of these machines and they they can do.  When you look through the magnifying stereo glasses built into a unique bi-fold cover of the book, you ll be able to see awesome CATERPILLAR machinery in action … and in 3D.

The technical quality of the photos and printing of the book is very good.  The photographer, Mark Blum, has an inspired eye and top technical skill. You really get a feel for the size and power of these big trucks and diggers when you see them photographed in 3D! The writing accompanying each image adds to the photos and will teach you how humans build their world. The hardcover book measuring 6-1 4 x8 contains 26 stereo images and a glossary. Published in 2001 and originally sold for $14.95.
