Sotheby’s auction of American Indian Art on May 18 2011 in New York resulted in total sales of $4,809,502 US. Eighteen of the lots were from the northwest coast. Of these, the highest result came from a horn bowl, only 8 inches long, but beautifully carved in the shape of a bird, incised with figures. In spite of an estimate of US$30-50,000, it sold at US$146,500. The bowl was formerly in the collection of the Pitt Rivers Museum in England, then a private French collection.
