Victims of Mad Science

This is from an (I think) Italian horror comic called Terror Blue. In later panels these girls are walking around as partial skeletons, so I do not think this procedure in the tanks is intended to be a healthy one.

This illustration originally appeared in a print magazine (you can see where the gutter has been imperfectly removed by the person who scanned it). Unfortunately it is not simple to identify the magazine or illustration. The style is typical of illustrations appearing (often without an identified illustrator credit) in Japanese bondage magazines starting with the venerable Kitan Club after WWII and continuing through a long series of titles like (in the 1970s and 1980s) SM Play, SM King, SM Fan, S&M Frontier, and many more. There is a profusion of scanned artwork on the web from these vintage magazines but little of it is searchable without Japanese-language skills. Here, for example, is a gallery of such artwork that includes this illustration plus a companion piece clearly by the same artist, and many more in similar styles. From the style of these pieces, I suspect they date to the 1980s, but that is close to pure speculation.

Whistle a merry tune

This anime-style robot catgirl whistling a musical note with her head tucked underneath her arm was uploaded to the Danbooru image board in 2008 and quickly spread to other boards such as Gelbooru and Sankaku Complex. Unfortunately, no information about the artist or an earlier source can be determined.

Who?

christmas-crucifixion
This art is titled “Christmas” as may be seen beside the artist’s signature, and is dated “05” — presumably for 2005. Unfortunately the signature itself is indistinct; it could be “tizmo” or “tizno” or “tilmo” or “tilno” or “tidno” or “tidmo” or a few other less-likely possibilities. It appears to have been uploaded to the Rule 34 image board in 2008. Unfortunately, no more information could be discovered.
