Graffiti Echoes Vietnam?

Recently while driving Tchoupitoulas--one of the few ways to escape Uptown--my wife saw some new stenciled graffiti on the side streets. We doubled back and found one wall that looked like a place where someone tried out stencils of dollar signs, spray paint cans with hearts on them, and a younger George W. Bush's head. Around the corner is a clown made scary by its sloppily painted red nose and blue tie.
