The beautiful colored cover on this volume belies the fact that that the majority of the prints are black and white, with just four pages of color plates in the middle of the book. Not all the black and white images are sharp, due to the era they were photographed in, so detail is not easy to see on many of the illustrations. Where this book makes a great research tool is in the large number of pencil sketches by Knox - it makes it easy to follow both thought and design development of his work. The major problem with this book lies in the poor binding - the instant I opened it, pages flew loose. The paper is thick and stiff, and the pages are simply cut and glued into a light, flexible cover, making them vulnerable to coming loose easily. I would not recommend this volume for purchase by a Public Library, but it is a delightful research book for private use, and my solution to the loose pages has been to get it bound as a spiral back book.
