A sectional diagram of a basketball rendered in white linework against a black ground displays four views of the sphere from different angles, labeled with figure numbers and technical measurements. The composition mimics a United States Patent Office document, complete with official header, patent number, and an inventor's signature at the bottom, lending scientific authority to this sporting equipment illustration. 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.
