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. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
