4th edition, first printing. 256pp, with five colour plates, eight further full page monochrome illustrations and maps to endpapers all by the author. Green cloth-covered boards, gilt lettering to spine. Top edge sprayed green. 8vo. Cloth very slightly pushed in at spine ends. Hint of shadowing to fore and lower text block edges. Internally neat, clean, bright and tight barring a mild splash stain in the margin of p214. In its original pictorial dust wrapper, a little bumped and slightly toned at edges and a slightly heavier bump to the lower rear edges, resulting in 3mm nick. The jacket is not clipped but has no price, suggesting this copy was intended for export. Dust wrapper now protected in an archival quality Mylar wrapper, fitted without the use of tape of adhesives. A very smart and presentable copy.
