I would like help in identifying a piece of Textile. ​I'm cleaning out my studio and I need help identifying some tapestry items from my old Berkeley days. I think it is Mexican and actually I know it is a hat that is meant to be wrapped around the head worn like a halo. It may be Central or South American. Do you know anything or a source I could go to? Or even a museum that would know and want it.  I want to sell it but I don't want it chopped up for belts. If it is a museum I'll donate. Thanks.
