Book Condition: Good+; bumped tips; dulling of the shadowbox spine label; foxing to textblock edges. No DJ as issued. Tan cloth boards and spine with gilt lettering on the spine and front board in black shadowboxes. Small crystal cross-section on the front board. 406 pp 8vo.

A clean presentable copy.
