On his way to work in the morning, street artist Mobstr would cycle past an average, graffiti-covered red wall in London. For years, he noticed that a city worker would paint over the graffiti with red paint, when it was below a certain line. For any graffiti above this predetermined line, the steadfast laborer would pressure-wash it off. “This prompted the start of an experiment,” wrote Mobstr on his website.
Over the course of a year, the artist graffitied the wall, waited for the worker to remove it, and repeated this cat-and-mouse game over and over again. Along the way, these two individuals went through several playful exchanges that culminated into one interesting, visual story with a satisfying end. Take a look at the images, below, of Mobstr's progress with the city worker.
