Unauthorized robot surgery

This image is reblogged from this 25 November 2014 post at Infernal Wonders. The art is self-attributed to someone who calls himself “peterpulp”, but a more genuine source would be found in my source post:

This appears to be a magazine cover by fantasy illustrator Dave Dorman (b. 1958), who has a website here. The original context for the illustration appears to have been this magazine cover:

The mechanics of tentacles

This image would be pretty obviously the work of Shirow Masamune (b. 1961) by style even if there weren’t attribution within the image itself. It is reblogged from a 16 January 2014 post at Infernal Wonders, and its origins on the Internet appear to go back to the now-defunct tumblr Random Forever Random, some of which is preserved in the Internet Archive.

Masamune has an official website here.
