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. Printed on clear acrylic and made to order in two sizes. A serving piece for the dinner party or a pop of color as a kitchen accent, carrying an independent artist's work instead of a big-box print.
