Painting the largest mural in Los Angeles is no easy feat, yet the London based graffiti artist INSA have managed to complete the task in his signature style. He recently flew into L.A. to paint the entire Art Share L.A. building, a two-story high building mind you, in his trademark heels pattern design. It might be hard to get an idea of size, look at the bus parked in front for reference. If you are in L.A., head down to the corner of Hewitt and 4th, to take a look at the actual 9,300 square foot building. Now, it might be hard to top this amazing work, but rest assured INSA would probably top this somehow in the future.
