Rolf,(posted 8772 days ago)As I said in my follow-up, the shadow proves that the shape IS the coat. My mistake was in thinking that the person(s) sitting on the far end of the bench was instead the triangular base of some kind of monument or something. The not-very-clear-on-my-screen "coat" looked like possibly a second (matching?) "monument"... perhaps a pair - one on each side of the walk.
Again,...VERY nice shot!
