This non-fiction ode to trucks features six kinds of workers and their trucks—a utility truck, a firetruck, a snow plow, an ambulance, a crane and a broadcasting truck—with four different parts of each truck properly labelled. The answer to each inquiring refrain is revealed under a gatefold, engnaging the reader in an informative guessing game. With lyrical (and factual!) text by New York Times bestselling author Toni Buzzeo and the expertly stylised art of Jim Datz, this sturdily constructed board book is perfect for curious and playful young readers.
