In the late 80' early 90's there was a company called artgraphics I think, that made these sheets that had silkscreened letters and numbers so you could put your name on your window and stuff. Then they got bolder and started making Sponsor sheets. My local track was running NASCAR style bodies on pan cars in a big concrete Talladega shaped track. Tide sued the pants off of Artgraphics. You would think that they would just work out the license and take the promotion. Guys were still doing Tide based NASCAR themes after that they were just heating up jugs of tide and stealing the real labels off of them. Tide cant sue tide. I guess they can but....
