And I really mean "unidentified". This sketch of an Elder Thing is a beautiful piece of work. It looks like a diary or notebook page from one of the scientists on the Miskatonic expedition to the Antarctic, including print-through from the opposite side of the paper. Sadly, no one seems to identify who actually made it. It pops up a few times on Pinterest, each ultimately pointing back to this address. I've run it through TinEye, Google reverse image search, etc., but can't find a match. Would anyone happen to know who the original artist is?
Update: Thanks to Terror of Death 42 and gndn for noticing the watermark pointing to the apparent artists website at robertsoo.com.
