Roger Priddy's First 100 Trucks and Things That Go is a large board book for young children, full of 100 photographs of all kinds of vehicles. Each colorful photograph is accompanied by the word, and the book is separated into themes--rescue vehicles, construction vehicles, on the farm, on the road, on the water, cars, and flying machines. This is a great way to build vocabulary for little ones fascinated by trucks, cars, diggers, tractors, and other things that go.
