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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
