The majority of the images that ProbBoyNick have been making with his reverse graffiti are animals. He has a unique way of removing the dirt to give the images on the side of the vehicles a sense of depth and realism. These temporary masterpieces must cause an interesting reaction when the driver returns to their vehicle. Check out some of the pieces below!
