@Billw12280, and thanks,
@Mrs. V, for introducing me to a phrase I hadn't learned before. Now I'll be looking for an opportunity to use it. [Edited for clarification: use the phrase, that is, not the gesture.] Besides the man's gesture, facial expression, and the coat that
James N. pointed out, there's another odd element to the picture. If you go to the eBay listing and zoom in on the second photo--the full-length one--you'll see an object in the lower right corner that appears to be draped over the man's arm at the elbow. Any idea what that is?
