I know a guy thats planning on making doghouses for medium size dogs and sell them on craigslist...well anyways.....his thinking of doing some art work on the side of the doghouse, like some flappy birds or super mario or zelda or some random legit looking artwork.....nothing would happen if perhaps he somehow makes a profit out of it or makes some money from it? His scared that some copyright agent or something might file a law sue for 1 milion dollars or something like that lol just asking.
