(See our FAQ for a description of our unique Sci Fi rating system.)
One minor reading create on the 'Astronauts' cover; slightest roll on spine, minimal chipping; no writing inside or out. Lots of gloss on both; pages lightly tanned. Overall, very clean for a pulp paperback that is almost half-a-century old!
