First American edition, sixth printing. Signed by F. A. Hayek on the front free end paper and inscribed to a former owner. Bound in publisher's dark aqua cloth with spine stamped in gilt. A touch of wear to the corners, several markings to text, otherwise Fine, in a Near Fine unclipped dust jacket (5th printing statement rubber over-stamped 6th printing on flap) with small pencil mark to front flap and light edge wear. A fantastic copy.
