Vintage wool rug likely made by the Andean peoples of Peru or Bolivia - probably a baby's blanket or frazada. Measures 38 by 40 inches.
Bought at an estate sale, so not sure of its provenance. It's a bit unusual ... I've seen lots of SA textiles with finely woven geometric patterns, woven from alpaca wool, but this is not typical - the weave is looser - possibly sheep's wool - and has a border. Given the pattern, wear, and the general "look" of the piece, I'd say it's 50-75 years old. Any informed opinions welcomed!
