Technical line drawings of a football helmet patent fill a dark charcoal ground, rendered in white ink with the precision of an engineering schematic. Multiple views show the helmet from different angles alongside detailed cross-sections and component diagrams, creating a layered composition that reads as both scientific document and sports 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.
