"This nonfiction ode to trucks features six kinds of workers and their trucks, with five different parts of each truck properly labeled. The answer to each inquiring refrain is revealed under a gatefold, seven in all, engnaging the reader in an informative guessing game. With lyrical (and factual!) text by New York Times bestselling author Toni Buzzeo, and the expertly stylized art of Jim Datz, this sturdily constructed board book is perfect for curious and playful young readers."-- Provided by publisher.
