Hello I have a Z. Garcia painting it looks like an American white man wearing the Mountain Man attire. I was wondering if this could be an original or is. And who is Z. garcia? He has paintings of Indians that I have researched.

Also have Z Garcia american indian painting. Has (2) feathers on right sid of head, red cloth around neck with large medalion hanging from it.Large mountains in back ground. Looks like scar on right sid of face. Probably purchased in Chicago art show in the 1970's -1980's, any ideas of value or where I can find out what ti is worth.
