Good. Boards are solid and the spine is square aside from moderate scuffing and staining, with quite a bit of sunning. Binding is slightly yielding with the beginning of separation at the back free endpaper. The pages are bright, crisp, and unmarked aside from previous owner’s inscription on front free endpaper, page separations at the frontispiece and illustration pages 61 and 71, and an odd crease at inner head of pages 67-80.
