This is your engine on acid.

Boris Artzybasheff being his usual creepy and kooky self. If not more so.

So is the engine on the right a loose depiction of the lovely Studebaker V8?

Also some Casco for the CASCOs. (You know who you are....)

I wonder if these are affectionate spoofs of Frank R. Paul "life on other worlds" illustration in the Hugo Gernback sci-fi magazines?

Since the car in the picture looks like a Cadillac, I would say the engine is a Cadillac.

HMMnn...just wondering if someone is using his engine as an acid distillery and drinking it while doodling???
