First edition. Large 4to. (316 x 248 mm), pp. xv, 561 + plates (inc. frontis.). Many illustrations to text. Hardback: dark blue cloth, boards gilt-embossed, gilt-lettering to spine, corners bumped otherwise very good. Dust-jacket, price-clipped, some fraying to edges and a longer closed tear from base of spine, grubby in places but still substantially good. Overall a handsome copy.
