A technical patent drawing renders three views of a bass guitar with meticulous line work against a weathered, aged paper background in cream and tan tones. The composition presents the instrument from front, side, and detail perspectives, capturing both the elegant curves of the body and the precise engineering of the neck and headstock with classical patent illustration style. 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.
