Alex Queral - "The process takes at least a couple of weeks to complete. He begins by sketching the famous person’s face on a piece of paper and laying it over the phone book, after that he uses a razor blade, patiently carving away at the thousands of pages that lie within phone book to create the 3D portrait. He then paints each face with a monochromatic wash to distinguish the portraits from the pages." http://www.projectsgallery.com/Queral.htm
