Coffee stains have been known to ruin perfectly good tables, and some of the doodles we worked on so hard at that staff meeting. However, sometimes the ring stains are purposely placed on paper, and used for actual works of art.

Coffee Stain Motorcycles is a series by illustrator Carter Asmann. Coffee stain rings act as wheels, while the motorcycle is then carefully illustrated around them. Try a few of your own at that next boring meeting… or you can just check out more works by Asmann here.
