From the publisher:
This book was the result of one sketchbook, using one pencil, from start to finish. I made a replica of that book page by page exactly as I drew within the book. There are 310 heads varying in style and expression. I hope this book inspires new ideas for you so when you observe and draw faces from imagination, photos and TV you will see how far you are willing to push it.
