A technical patent drawing from 1928 displays baseball equipment in meticulous black line work against a clean white ground, with a bat, ball, and detailed cross-sectional diagrams of the ball's interior construction arranged in a methodical grid. The composition carries the instructional clarity of early-twentieth-century patent documentation, rendered in precise pen strokes that emphasize function and engineering innovation over decoration. Constructed from woven polyester with a soft microfiber lining and a sturdy zipper, made to order for 13 and 15 inch laptops. Everyday protection carrying an independent artist's work, not another plain black sleeve.
