Basket w/ Quills

I'm not sure if this is 'tribal,' but this is probably still the best forum.

It's bundled grass and finished with two 'stripes' of porcupine quills.

Approx 7" tall and 7" wide (18cm)

Any leads as to origins?

Found at a vintage show in Portland, OR.

Thank you!

The basic shape and materials look African, and, although it is hard to see their size, the quills may be from one of the African species. They are larger than North American porcupine quills, and they are striped -

I have not seen it in traditional use, but it might be a newer novelty style made for sale.
