Gads, I was two months old when this hit the newsstands. Astounding Science Fiction, was the best magazine of science fiction pulps at the time. The artwork (from some of the top artists of the day) relied more on the story for their inspiration than sex appeal. Other magazines like Planet Stories relied more on pointy-breasted, scantily clad women featured on their lurid covers for sales rather than good authors, although they did have a few of the better writers. Magazines back then were usually sold in drugstores in racks near the soda fountain. Young men and teen boys bought most of the magazines so that sex appeal was a real factor in sales.
Stories of that era, including Hubbard’s (especially Hubbard’s) didn’t wear very well over the years. Writers back then didn’t spend much time on technology explanations since there was darn little technology around. The language, the plots and the ludicrous ignorance of basic science make these stories hopelessly dated.
