A vintage patent diagram shows a baseball at the top with detailed stitching patterns, followed by two unrolled views of the ball's construction and seam layout below. The composition is rendered in simple black line work on a weathered cream background, capturing the technical precision of early 20th-century patent illustrations with their characteristic sparse, informational style. 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.
