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 on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
