This was a nicely rendered elephant last time I saw it. I’m not sure if it has been defaced or if the paint-over is part of a planned revision. There were no apparent tags showing through the thinly rolled white paint.
This does remind me of one of the problems with well-intentioned public murals, though. If someone does decide to vandalize them, they are a lot harder to clean up than flat-colour walls would be. More expensive, too.
