I keep thinking that if we could see to the figure connected to the hand at left, it would turn out to be Marcel Duchamp! It seems to me he would really have enjoyed hiking to Point Sublime in Yellowstone (for sure choosing the trail that takes one via Artist Point) just in order to be able to snap this pic with his hand framing the view, and to be able to caption it as such. For me, this is a small, perfect thing.
4 1/3" x 2 2/3". Good condition, with a little curling but it should flatten out.
