Green cloth-covered boards, bind stamped, gilt titles to spine, 368 pages in all. Illustrated with diagrams, sketches and from photographs, and with three fold-out maps to rear. Condition: A very little foxing to the margin of the page opposite the first map, one instance of a pencil marking in the margin- it is possible there are others but I have not found any- and some wear to the boards. Anonymous decorative bookplate to front paste down and previous owner’s name to front free end paper. Overall a firm, bright copy.
