Preschool kids won't know what a "lenticular" panel is (parents probably won't know, either)--but everybody will have fun seeing how it works! Move this book slightly, changing your angle of vision in relation to the cover, and the panel presents first one picture, then another! Keep varying that angle of vision and the picture keeps changing! This big board book has an inset lenticular panel that shows a clever little boy. Every illustrated board page has a rectangular cut-out to accommodate the panel and to serve as a words-and-pictures frame around it. In Yes! or No! a little boy's facial expression and body gestures change from agreement to disagreement Kids who open this Making Faces book to any two-page spread will find a question. For example, Kitty and Bunny both want to push a big red truck, but only one at a time can push it. Should they take turns? Kids can move the book so that the little boy in the panel says either Yes! or No! (Ages 3-5)
