A technical patent drawing renders an American football in cross-section and plan view against a dark charcoal ground, with fine white lines detailing its internal structure, seams, and geometric proportions. The composition pairs the oval profile with a circular top-down view, accompanied by handwritten annotations and an official patent stamp that anchors the piece in early 20th-century industrial 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.
