Name that Artifact

One of the more interesting items uncovered on Falls Road is a mystery item. I've done some internet searches, but I haven't found anything that matches what we have so I'm hoping someone out there knows what this is. If you do, please leave a comment!

The first picture is to provide the scale so you can see how small the face is in reality. The second provides a better shot of the face. It's a piece of darkly glazed stoneware and the poor guy is missing large chunks of his face. Hopefully someone recognizes him anyway.
