Told from the perspective of a construction worker to his crewmates, (Hey, you guys! Let's get to work,") Machines at Work depicts the activities of the builders and building machines that toddlers love so much. Simple text depicts the demolition of an old building and the construction of a new one. Kids will love Barton's trademark bold colors within thick black outlines, and adults will be glad to see women in this multiracial construction crew.
