Two technical drawings rendered in white lines on a charcoal chalkboard ground show the mechanical components and assembly of a basketball hoop system, dated October 29, 1963. The schematic diagrams detail the apparatus from multiple angles with numbered parts and annotations, capturing the industrial precision of sports equipment artwork with the aesthetic of vintage patent documentation. 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.
