I'm not sure what's going on in this cover by Howard V. Brown, but that looks like a mosh pit in the background. Well, they do say that science fiction can predict the future. Inside this issue of ASTOUNDING STORIES are stories by some great writers: Jack Williamson, Murray Leinster, Stanley G. Weinbaum, Nat Schachner, Raymond Z. Gallun, Ralph Milne Farley, and Wallace West. F. Orlin Tremaine was still the editor at this point, but John W. Campbell has an article in this issue. The whole issue is on-line at the Internet Archive, so I guess if I'm curious enough about that cover, I can find out.
This is the first issue of THRILLING WONDER STORIES after Ned Pines bought WONDER STORIES from Hugo Gernsback and changed the title. That's certainly an eye-catching cover. I don't know the artist. Equally eye-catching is the lineup of authors in this issue: A. Merritt, Ray Cummings, Stanley G. Weinbaum, Otis Adelbert Kline, Paul Ernst, Eando Binder (Earl and Otto Binder), Arthur Leo Zagat, and Mort Weisinger, who also happened to be the editor. That's just an excellent group of writers. You can read this issue on-line here, along with a lot of other issues of THRILLING WONDER STORIES. You know, between the issues I own and all the issues that are available on-line, I could just about spend the rest of my life reading pulps of all kinds. And when I retire, I might just do that.
