A vintage patent drawing depicts two tapered baseball bats rendered in precise technical lines, flanked by detailed cross-section diagrams showing the bat's construction from multiple angles. The sepia-toned paper and formal patent notation create an antiquarian aesthetic that celebrates the engineering precision underlying America's pastime. 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.
