Just another example of the many legends here on earth. There are those who think the yeti is real, but of course, no concrete evidence has ever been found of their existence. Regardless, if a cult of yeti worshipers made a creepy mask of their likeness, it might look something like this. Interesting side fact, there is a place in Tibet where such a cult actually exists, and they claim to have real yeti artifacts such as hair and so on. Naturally, no outsiders are allowed to enter the inner sanctum, much less run DNA tests on the hairs. If you ask me, it sounds highly dubious, and i am willing to bet that someone is getting rich off of that...
