Today I came across
the website of this really cool artist, Alex CF, who creates fake specimen display cases with horror and fantasy animals and such, in the style you might find in old museums or cabinets of curiosities. The website describes it as "cryptozoological scientific art". Sometimes it is whole sets, with documents, skeletons, preserved specimens, tools and all sorts of stuff and they come with short stories of a sort explaining the fictional background. I especially liked
Cthulhu Specimen Box,
The Lycanthropy research of Edward Harrell,
Severed “Draco Alatus” Head and
Infant stillborn Draco Alatus,
Expedition to the Plateau - Lost World Exploration Case and
Experiments in extra dimensions; The Cheshire cat, but really you should browse the whole site. (Obviously due to the nature of the art the displays are slightly gory.) I only wish the photos of the works were in a higher resolution, because you can't make out all the awesome detail and read the text in the documents on the site.
