Technical drawings of fishing rod components and mechanisms fill this chalkboard-style composition, rendered in white lines against a dark charcoal ground. The patent illustration captures multiple views and cross-sections with the precision of an engineer's hand, creating a layered, instructional aesthetic that celebrates the ingenuity of angling equipment artwork. 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.
