A technical patent illustration displays an exhaustive cross-section of golf equipment and anatomical diagrams, with the word "GOLF" prominently lettered at the top in serif typeface. The composition is rendered entirely in black line work on a cream ground, featuring dozens of labeled mechanical drawings, club head sections, ball construction details, and swing posture studies arranged in a dense, encyclopedic layout. 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.
