A hardcover book by Daniel Daniel (yup) it is only a step abov a pulp in quality it was cheaply made to maximize a quick profit as opposed to a quality book designed to last, but it's not unauthorized as Ruth wrote the foreward. Heavy acid content means this is a tough book to find intact. spine is splitting and some pages are starting to pull away, but it's still all there. The collest part of the book is the Conlin photography throughout.
