On the road, in the air, on the town, at sea, and on the construction site: The world is full of wonderful moving machines—and so is Indestructibles: Things That Go! Each spread includes simple text and call-outs to introduce babies to the many different vehicles that fly, drive, sail, race, dig, and dump. What an exciting, fast-moving world we live in, baby! Printed on a unique nontoxic, paperlike material that holds up to anything babies can throw at it – gumming, spilling, dragging across the floor – Indestructibles are the little books that could. And if they get dirty, just rinse them off. With more than two million copies in print, Indestructibles are the books built for the way babies read.
