Iteration of a classic tube girl theme

Anatomy of the heart
Victims (?) of science

This is a tube girl in this Japanese-language gallery while I was researching another post. What made the illustration stand out for me was its internalization of a classic tube-girl trope. You see, back in the days-that-would-have-been-bad-but-at-least-we-had-pulp-magazines, we often encountered illustrations like this one, which I posted on 14 August 2017: or this one, which I posted on 3 April 2017: or finally this one, which I posted on 14 October 2016:

Notice the common theme? The artists working at that time couldn’t depict nudity (at least, not without running into legal and commercial problems), so putting girls in tubes gave them a way of implying nudity, but putting having the naughty bits concealed by metal rings that were presumably part of the tube’s construction, or occasionally steam or bubbles that were part of the “experiment” she was undergoing.

I doubt that the artist who made the primary illustration in this post faced any such constraints, but the glowing rings around our girl seem like a neat tribute to the older tradition. Provenance is very uncertain, but there is at least a version of the illustration that has captions, if any of you read Japanese.
