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 to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
