Readers explore the concept of layering and collage with this interactive exercise in composition. Each clear acetate page features a single element in the leaf pile, though some are not leaves at all! As readers turn the pages, the leaf pile is deconstructed piece by piece on the right side, and reconstructed on the left. Younger readers will enjoy the seek-and-find aspect of the hidden objects, while older readers might experiment by adding their own images between the pages. A key at the back provides the names of each kind of leaf shown. Inspired by the Whitney Museum's approach to looking at art, these books provide a new way to look at the world.
