Feathers and Arrows, Wonderful, Unusual 19th Century Stumpwork Style Embroidered Portrait on Painted Silk

An unusual one, which I know from the dealer I purchased it from came out of a notable New York collection. The manner of the embroidery draws closely on early 19th century "stumpwork" embroideries on silk, which combined raised raised embroidery with drawn or painted elements (especially faces.) This is certainly later, late 19th/early 20th century I believe, and certainly American, depicting what I take for a Native American woman in wonderfully feathered headdress and dangling earrings, a quiver of arrows behind her. A bit hard to tell if executed on cotton or silk,I think the latter, with some use of graphite on her face and arms, and the painted elsewhere. Looks to me like probably some bleeding to the color at some point, which makes the ground all very painterly, a swirl of orange and red and gold. 

13 3/8" x 11 3/8" framed. Sight 8 1/2" x 6 5/8". Framed as found, with cardboard board backing added and stapled on at some point. Seems likely this saw some moisture at some point, but seems dry and stable now and I think really very wonderful.
