Here for the first time is a book about vehicles for toddlers in the same format as the highly successful Peek-a-Moo! and Peek-a-Boooo! Preschoolers will love lifting the oversize flaps to play peek-a-boo with cars, planes, submarines, and, of course, trains. Guess who? Peek-a-toot-toot! honks the tugboat. Guess who? Peek-a-vroom-vroom! revs the race car. With its playful text and bright and friendly illustrations, Peek-a-Choo-Choo! is the perfect introduction to ?things that go? for the youngest traveler.
