better pics would help, ok I found it It's by Bev Doolittle (not sure she is Native , but the subject is) , the original was a signed limited edition(Much larger) 32 1/2" x 19 1/2" was limited to 1500 copies , I believe this is a re-print , still a very nice image! And she's quite famous now! The original was done in 1982 .Hope that helps! Good luck! (feel free to ask me for any info if you decide to sell other things, I an always take a loo, just message me) I used to sell Bev Doolittle's work at a Frame shop I worked at years ago. Thought it looked familiar!!
