A detailed technical patent drawing displays three views of a tennis racket alongside cross-sectional diagrams and component specifications rendered entirely in black ink on white paper. The composition captures the mechanical precision of early 20th-century patent illustration, with fine lines and numbered annotations documenting the racket's construction from handle through the woven string head. 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.
