Graffiti buffs and street artists battle authorities and clean-up crews all the time, but they’re rarely as long or as good-natured as this one. A London-based street artist who uses the moniker Mobstr played cat and mouse for nearly an entire year with a determined and persistent cleaner. He finally conceded defeat and documented the battle on his site, mobster.org. “I cycled past this wall on the way to work for years,” Mobstr wrote. He noticed that when the surface was tagged in the red area, it was painted over, and when it was tagged on the bare brick, it was pressure washed. This gave way to full on battle that started on July 17th, 2014 and continued until just a few days ago. The unspoken dialogue between the Mobstr and his nemesis is very funny, and we’re glad to see the cleaner emerged victorious. Check out how it went down. Even if you hate graffiti, we dare you not to laugh!
