LONDON — A British graffiti artist's year-long battle with a local council – and how that squabble transformed an otherwise unremarkable brick building – has been recorded in a gloriously amusing photo series.

The anonymous Mobstr, who runs a website that "documents images of work found on streets and other locations by persons unknown", gave Mashable permission to publish the series here.

"I cycled past this wall on the way to work for years," wrote Mobstr in an introduction to the photos. "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. Below is what transpired over the course of a year."
