This sketchbook gives you the opportunity to learn how Harper captured his subjects with the fewest possible visual elements. For each of the 28 birds featured herein, we've included a four page presentation. On the first page you will find line drawings that show a three stage process for recreating Harper's image. The line drawings build on each other. The first one presents the most basic shapes, second further develops the form of the bird, and the third completes the image with all the details.
