Ace Double: City on the Moon by Murray Leinster/Men on the Moon by Donald A. Wollheim 1958; good, vintage, mass market paperback book; the book is clean, tight, square, and free of any markings showing well thumbed and age-toned pages (see photos) and scuffing along all page edges (see photos) but otherwise showing only light additional evidence of having been previously gently read; book cover (wrap) shows moderate shelf wear, including creasing along the spine (see photos) and wear along all page edges (see photos) and to the corners (see photos) but remains in good, vintage, condition.
