Detailed technical drawings of fishing lures and fly-fishing equipment fill this chalkboard-style patent illustration, each labeled figure rendered in white linework against a deep charcoal ground. The composition arranges eight distinct lure artworks in a grid formation, capturing the precision and ingenuity of mid-century sportfishing innovation with the aesthetic of a vintage blueprint. 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.
