My Carry-Along Sound Book Trucks is a sound board book for babies and toddlers on the perennial favorite subject: Trucks. Each title features photographs of busy trucks, with fun rhymes for adults and children to read out loud together. The key selling point, however, is the integral four button sound bar - children can look at the pictures, listen to the rhymes, then press the buttons to hear the noise that each truck makes. This title is die-cut to shape, with a fun carry handle.
