Since most young children enjoy looking at photographs of their peers, Pamela Harris has found an appealing way to introduce opposites to toddlers. She uses photographs of children to demonstrate the concept and here the children's faces become the artist's canvas. With just a few words per page, a rhyming text points out the opposing features, beginning with "a hot face / a cold face / a shy face / a bold face." Engaging, remarkably unposed photographs show a wide range of children of various ages, along with a few adults who were needed to illustrate "an old face" and "a bearded face." The photographs are large and clear enough so that the book could be easily shared as a group read-aloud, although individual children will want to spend time pouring over the pictures, trying out some faces of their own.
