Such was the demand for Moore's Mars works that these books were re-published in a cheaper format very shortly after their initial publication. While not expensive true firsts, these examples nonetheless share the excitement and exuberance of the splendid original jacket illustrations, and will make a handsome addition to any collection. The jacket here is generally very good to fine, although price clipped, with a few nicks and bumps, normal wear, but no major losses. The books is all very good, very clean and tight, with a gift inscription to the front paste down.
