Again the big, big full-page, full-color illustrations that the toy truck set will love, with technical information for older brothers. Trailers, busses, automobile carriers, a fire truck, a d truck, etc. are pictured and described with reference to use and variations in construction. The story of a truck driver's day is outlined simply and in easy prose, but the mechanics of an engine is solid material which may baffle reading mothers. Picture book size with laminated cover.
