Black? White! Day? Night! : A Book of Opposites by Laura Vaccaro Seeger

This is an ingenious treatment of opposites for pre-K through maybe first grade. Using flaps with holes cut in them to demonstrate opposites, the author has created a clever and original book. A black bat turns out to be the smiling mouth of a white ghost when the flap is lifted.Narrow looks like a thin yellow line on orange until you lift the flap and see wide, which is a long swath of yellow. This is a book that has to be seen and experienced to be appreciated. The design will be a problem in a library where it will get a lot of circulation, but it deserves consideration as a best book anyway. The drawings are simple and the colors bright, just the right combination for young children.
