Mouse is small, to be sure. And Tortoise is big (relatively speaking). But Pelican is bigger than Tortoise, and Zebra is bigger still. In an engaging, interactive novelty board book, Mary Murphy turns her bold, high-contrast illustrations -- perfect for visual stimulation -- to a first look at size relationships. Babies will be happy to lift the graduated shaped pages to see a series of animals that get increasingly bigger -- and learn which creature causes the biggest reaction of all!
