Three technical drawings of a fire truck appear in white linework against a charcoal black ground, dated September 28, 1939, showing side profile, top-down, and isometric perspectives with patent notation and inventor's signature. The composition captures the mechanical precision of vintage industrial artwork, rendered in the stark contrast and technical clarity characteristic of early 20th-century patent illustrations. 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.
