A technical patent drawing for a baseball diamond layout appears in white linework against a charcoal black ground, rendered in the style of a 19th-century inventor's blueprint complete with handwritten signatures and official patent markings. The composition captures the essential geometry of the playing field with mechanical precision, evoking both the scientific rigor of patents and the timeless strategy of America's pastime. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
