Vintage patent diagrams for firefighting equipment fill this composition, rendered in detailed black line work against a clean white ground. Helmets, axes, ladders, hoses, and mechanical apparatus are arranged in a technical schematic style, evoking early 20th century industrial documentation with scholarly precision and historical authority. 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.
