must-have ! Skull made by unknown craftsman signed box limited to 33

Don't ask - I don't know - sorry but I just picked this up last week as part of a comic book collection - I would say it weighs about 2 pounds and is made of a incredibly dense material that is hard as rock but not rock itself. This was part of a limited run of 33 and the box is signed. The writing on the skull seems to spell either "Mofit" or "Profit" (see photos), but neither of these could be correct. Despite this it is a terrific looking skull - I've included photos of it next to my hand so you can better understand ifs size.
