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. Water-resistant polyester, hookless and cut extra long to fit any bath, machine washable and made to order. It turns the bathroom wall into the room's best feature.
