A golf driver patent from 1924 unfolds across a classic blueprint grid in crisp white line drawings against a deep cobalt ground. Multiple technical views show the club head from different angles with precise measurements and annotations, capturing the mechanical precision of early golf equipment artwork with the formal rigor of an engineering diagram. 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.
