The street artist Mobstr found a wall in East London that was partially red and decided to have a little fun with it. It turned into a battle of wits that lasted an entire year.
I cycled past this wall on the way to work for years. I noticed that graffiti painted within the red area was “buffed” with red paint. However, graffiti outside of the red area would be removed via pressure washing. This prompted the start of an experiment. Unlike other works, I was very uncertain as to what results it would yield. Here is what transpired over the course of a year. --Mobstr
