Black, Skull-like Tiki Mug - Need Help Identifying

Hi All,

A friend who's an eBay seller, but not a tiki mug collector, nonetheless stumbled upon this nice collection at an estate sale last weekend and was smart enough to realize they might be worth money:

We've identified them all EXCEPT these two black tiki mugs with skull-like teeth. No marks. Anyone ever seen these before?

hobbyist mug. i hope this info is worth a suffering bastard. :)

Yep, I've got one. I love it. I think Tiki Kate has been looking for one.

Thanks kingstiedye, SilverLine!

Those examples on Ooga Mooga with the thinner glaze and sharper details sure push it over into "skull" territory more than "tiki". I like the glaze on SilverLine's though too. Ok - hobbyist skull mug it is.
