A hard cover edition, signed by the Author, with bottle green boards, gilt lettering and illustrated, unclipped dust cover. There is a back ink inscription on the inside front page and a black ink inscription and dedication by the author on the title page. There is some foxing and toning but the text, black and white diagrams and colour photos are clear and legible. There is some rubbing to the edges of the book and dust cover. There are some tears and staining to the dust jacket. Now in a clear, removable cover to protect from damage.
