A golf driver patent from 1924 unfolds across a classic blueprint grid in crisp white line drawings against a deep cobalt ground. Multiple technical views show the club head from different angles with precise measurements and annotations, capturing the mechanical precision of early golf equipment artwork with the formal rigor of an engineering diagram. 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.
