1970. No edition stated. 350 pages. Illustrated jacket laminated to boards. Includes photographic plates. Seems a little like an ex library copy but no actual library markings. Pages have slight foxing, tanning and minor thumbing. Previous owner's inscription to title page. Cloth reinforced hinges. Dust jacket is taped to boards, so board condition hard to assess. Unclipped jacket, laminated to boards, has light edge-wear with minor tears and chipping. Mild rubbing and marking.
