Vintage patent diagrams for basketball equipment fill a black ground with white line-drawn technical illustrations, including hoop assemblies, ball cross-sections, nets, and court layouts rendered in the precise, annotated style of early 20th-century patent documentation. The composition arranges multiple views and components across the surface with small text labels and patent dates, creating a dense, educational quality that celebrates the sport's mechanical ingenuity. 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.
