I bought two original oil paintings by David Humphrey Miller back in the late 70's from Kay at her shop at Mount Rushmore for an investment. One of the paintings is called Lizzie Yellowtail and the other is called Henry Little Coyote. Kay had bought these two painting directly from David back on 10/17/72. I have a the letter from him on the back of one of the paintings. I also have one of his prints of that I enjoyed "Ben Black Elk" print 105/300. I am in the midst of looking to retire and thinking I might want to sell these paintings. I am not even sure I should be writing on this web site with this info. Please respond. Thanks for your interest.
