A technical patent diagram for a golf club is rendered in white line art against a charcoal black chalkboard background, showing detailed cross-sections and measurements across five labeled figures. The composition balances scientific precision with the worn, authentic texture of vintage patent documentation, evoking early-twentieth-century industrial illustration. A glossy-finished set of four, made to order. A bold way to bring an independent artist's work into the room without committing to a large piece, whether on the dining table or the bar at your next party.
