Thrilling Wonder Stories was still going strong in October 1949, as evidenced by this Earle Bergey cover. Strangely, though, much of its art was uncredited, at least according to this issue’s entry at the Internet Speculative Fiction Database. That’s a pity, since I would enjoy knowing who did this illustration for “Lure of Polaris” by Wallace West (1900-1980).
This issue of Thrilling Wonder Stories is available to read or download at the Internet Archive.
That’s my kind of action cover!
