A technical patent diagram for a baseball game apparatus occupies the center of this aged document, rendered in black ink on a cream ground with handwritten signatures at the bottom. The composition captures the mechanical drawing style of late 19th-century innovation, complete with numbered reference points, detailed annotations, and a patented date of August 9, 1887, evoking the intellectual curiosity of early sports engineering. 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.
