This cover by Malcolm Smith for the April 1942 issue of Fantastic Adventures definitely gives off a tube-girl vibe. The interior art didn’t much impress me, but you are welcome to see for yourself as this issue of Fantastic Adventures is available to read and download at the Internet Archive.
The dame holding the gun on Harold W. McCauley’s cover for the July 1943 Amazing Stories is more suggestive of crime pulp than science fiction…until we notice what looks surprisingly like a tube girl in the background, suggestive of rather more exotic goings-on.
Virgil Finlay’s interior art is featured in this number, with an appropriately surreal illustration for Alexander Blade’s story “Carbon-Copy Killer.”
Another example of ICUdhara’s work, in which one of the unfortunate would-be explorers of the abandoned Euphoric State Insane Asylum has been captured by the sinister Dr. Vragov, confined in a transparent tube, and radiated into goo. As with its companion published yesterday, it is available in large size. Right-click to download.
It is with pleasure that I learned today that LN Bey, a writer and fan of BDSM and S/M erotica, is also a tube girl fan, and just yesterday contributed a post about the trope, containing both intelligent critical discussion and several of the finer historical examples of the trope (as well as some surprising contemporary ones as well). I encourage you to follow the link above and check it out.
Oh and by the way, LN, here’s one for your enjoyment, spawned from one of your historical examples, but given a contemporary feel by the artist.
How sharp my regret I don’t have a higher-quality version of this cover, given how it exhibits one of my favorite visual tropes. It was painted by Walter Popp for the August 1953 issue of Startling Stories. Interior art in the issue includes this piece by Ed Emshwiller, illustrating Theodore Sturgeon’s “The Wages of Synergy,” which is about as symbolically representative of Erotic Mad Science as any piece of pulp art I have yet found.
Of course you can’t be a really first rate sci-fi pulp unless you have tube girls. I’m pleased to note that while the interior art got thinner over time, Imaginative Tales did go there on two of its covers. Here’s May 1957, done by Lloyd Rognan (1923-2005).
