Graffiti on graffiti

The torrential rain of the morning paused at noon and we had a couple of hours of sun. At lunch, I wandered around the back alleys of the financial district amazed by the graffiti.

Someone saw me taking pictures of the pictures and pointed out this art taped to a wall. He enjoyed the discovery and so did I.

Is it a sketch for tonight's spray art? Is it art for art's sake? An anonymous art show.
