Forrest and I ate at F. McLintock's tonight. While waiting for our food, I sketched the buffalo head hanging on the wall.
This here is a photograph of the napkin on which I sketched said buffalo. Then I overlaid a brown color uniformly over everything with the GIMP. I'll try scanning it sometime, see if the quality's any better.
Update, 12:15 AM: I found this photo here of another buffalo head, so you have something for comparison.
