I am a TV producer at South Dakota Public Broadcasting (the PBS affiliate here) and I am working on a segment about bison and their importance to Native peoples. I saw the petroglyph image of 2 bison and am seeking permission to reproduce it in my broadcast. We are a non-profit and while I cannot pay you, I would certainly credit your artist or company for providing the image. I would so appreciate an answer as soon as possible. Thank you.
