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. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
