I have a oil painting of a kneeling indian on black velvet canvas. I can not make out the signature. On the back of the frame is stamped HECHO EN MEXICO which I assume was made in mexico. The photo includes arrows,animal skull and three feathers in his headband. Any information on this would be of great help. Thanks.

Can you post a picture of the painting? If you can, include a zoom on the signature (assuming that it has one and it just isn't legible).
