A vintage patent diagram from 1924 illustrates a baseball and related equipment in precise technical drawings rendered in black ink on aged, cream-colored paper. The composition features a large spherical baseball at the top with detailed stitching, accompanied by smaller studies of a curved bat and measurement scale, all labeled with patent information and inventor signatures in a formal, scientific manner. 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.
