I have an original watercolor of native american chief on horse; he holds a shield, spear w/hatchet, his head dress is blue, orange and red I think he's comanche. I cannot identify the artist because the signature is difficult to read. My research has lead me nowhere... can someone recognize this name: looks like Paul Ganoukip or refer me to a site that it would be better to research

If you could post the picture and a blown up signature here that would be helpful
