A cowboy’s first view of an automobile?

I saw a painting some time ago that I am trying to recall. It shows a cowboy looking at an automobile for the first time. I want to use the situation in a book that I’m working on now and want to see the painting again. I think it is by Russell or Remington. I have looked on the web, probably not very efficiently, without success. If this rings a bell, please held me identify the painting and its location, or someplace on the web where I can see it.
