Four technical drawings of electric bass guitars appear in white linework against a charcoal background, arranged in a vertical patent-style layout with front, side, and detail views that reveal the instrument's construction and artwork. The monochromatic palette and schematic presentation evoke a mid-century technical document, creating an architectural quality that celebrates the bass guitar as both functional tool and iconic form. 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.
