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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
