Broadside measuring 25 by 18 3/4 inches. A map showing the different parts of a book, illustrated with three black & white photographs showing a hardcover book, softcover book, and a book's interior. The photographs are labeled with every aspect of book structure, from the headband and colophon, to the outside margin and front flap of a dust jacket. The whole is bounded by a border printed in red. Few small creases and smudges, else fine.
