woven basket

It is hard to say exactly, at least without close-ups of the material used, but this appears to be what is called a "simple coiled raffia basket," of a vintage age, probably 1960s- 70s. While the decoration might seem to imply a Mexican or Peruvian origin, most baskets of raffia grass are made in places like Afghanistan and Uganda. Vintage pieces tend to be priced between $10 and $35. To see how they are made, or to check on a far, (far) more exact opinion of age, style, and value, by real basket fanatics, I would check with the good folk over at Basket World, on Flickr.com. You might double your chance for a fast buyer that way, as well. (I'd post the URL, but the darn thing is LONG!)
