I had been looking around for art for the my son's room and I couldn't find anything that was both reasonable and stylish, so I decided to make my own. I picked up some canvas and oil paints from my local art supply store. I just roughly sketched out trucks, cars, trains and a tractors and then painted then in shades of grey. They are not perfect but I think they add a nice detail to the room and my kids loved them. I framed them with Ikea Ribba Frames in white.
