Very good, vintage, mass market paperback book; the book is clean, tight, square, and free of any markings showing lightly thumbed and age-toned pages (see photos)but otherwise showing only light additional evidence of having been previously gently read; book cover (wrap) shows light shelf and corner wear, including light age-toning (see photos) bumping to the head and foot of the spine (see photos), and a significant closed tear to the head of the front cover of At the Earth's Core (see photos)but remains in very good, vintage, condition.
