Cultural Bazaar in Amherst

Could someone please explain what does not count for "indigenous" cultural objects, please? We went to the bazaar, and (though many folks came in the interest of cross-cultural exchange), there were some vendors selling mass-produced products. So, is a factory-produced mask an "indigenous" cultural representation. Probably. But that forces the "real" vendors -- those who are crafting by hand -- to lower their prices and not get the money that their work deserves. You comments are welcome!
