A technical patent diagram for a baseball game apparatus occupies the center of this aged document, rendered in black ink on a cream ground with handwritten signatures at the bottom. The composition captures the mechanical drawing style of late 19th-century innovation, complete with numbered reference points, detailed annotations, and a patented date of August 9, 1887, evoking the intellectual curiosity of early sports engineering. 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.
