One of the most interesting parts of this book was the detailed information on the techniques of producing aging effects, fly spots, and staining or dirty varnish. It was fascinating to ride along as the author tried this or that to mimic certain traits of various artists. His appreciation of the various art styles comes through clearly. Yet I find it contradictory to then cheapen the art by passing recreations off as the original work. Still, my own moral view point did not lessen my enjoyment of this book.
