Right now I'm loving Xander Walker's spray painted car art. It's gritty and has a street vibe about it, but the stencils and color blocking also give it a graphic quality. Right now his followers consist mostly of auto enthusiasts, but I think I'm going to turn the tides and give him a new flock of design groupies. I can totally see a series of these hung up in a boy's room. At around $30 a pop, for an actual signed and numbered print they are really well priced. Check out his Etsy shop.
