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 on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
