There are "tells" in the portraiture of the two faces, but I'm not enough of an anthropologist to recognize which culture is present here. Even if it is a tourist piece, it would pick up on the traditional heroes and devils of that culture. It's an interesting mystery if the right person gets a look at this. I think the guy in the peaked hat is some sort of evil intruder and the other is a warrior opposing him, hence the creepy tension. This looks like work from Africa, South or Central America, or maybe the Pacific Islanders or Indonesia. If I had to guess, I'd say Peru, but I'm really in the dark here.
