White technical line drawings of a fire hydrant appear across a dark charcoal background, rendered in the style of a vintage patent schematic with detailed mechanical views and cross-sections. The composition balances multiple perspectives of the industrial object with handwritten annotations and official patent markings, creating a cool, technical mood that celebrates industrial artwork history. 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.
