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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
