A snapshot/slice of a time long past...notable that the most famous story in this issue of Weird Tales would be the most famous and among the most influential stories to be published in any of the issues cited here, one which posits that "Jack the Ripper" has found a means of achieving literal immortality through his crimes. Got a top-line banner, though not the cover illustration (albeit, to be fair, the story is not so very much Newsstand Illustration-friendly for the times).

The most famous story here, I'd say, is the Wellman. I've certainly seen it collected and anthologized the most. Though the Sturgeon is probably a not too distant second...

Fantastic Adventures [v5 #7, July 1943] (25¢, 212pp, pulp, cover by Robert Gibson Jones) []
Editors:- B. G. Davis - Editor: Fantastic Adventures, May 1939 – Jan 1947.
- Raymond A. Palmer - Managing Editor: Fantastic Adventures, May 1939 – Jan 1947. (Palmer was the actual editor of the magazine at this time. TM)

This issue can be read here. ISFDB index here. The Catherine L. Moore story would be the best remembered of the new fiction in this issue...even if by default. Chambers has had a spike in interest in part from television taking elements from his fiction and/or name-checking it in such series as True Detective, From, and Good Omens, the last in its turn based on the novel by Terry Pratchett and Alan Moore which also pays homage to Chambers, and apparently also Chilling Adventures of Sabrina, which I have yet to see.
