Costume figure

I am wondering if you can rule in or out the costume of this wood statue that I have come across. It doesn’t look to me like Native American but resembles more South American natives. Or it could be some other culture that I am not aware of. There is writing on the bottom but I can’t decipher what it says. I see all kinds of letters LOL.’
