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. Crafted from durable canvas-like poly-poplin and made to order, double-stitched with a cotton webbing strap. The everyday haul, from groceries to the beach, carrying an independent artist's work.
