Tarahumara nesting baskets 12 pieces set, vintage Mexican traditional hand crafted sotol cactus baskets

This is the nicest set of Tarahumara baskets I've ever seen, TWELVE baskets perfectly nested into a tight flower shape. Smallest basket is about 3", largest basket about 8" in diameter.

These are unmarked, vintage, brought back from a trip to Mexico. I'm not sure of their exact age, none are marked or signed. I believe these are the sotol fiber - but Indian baskets aren't my specialty really. All twelve baskets are in excellent condition.
