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. Sewn from a durable canvas-like exterior with a soft lining and made to order, in three sizes up to one that fits a tablet. A catchall for toiletries, art supplies, or small electronics, carrying an independent artist's work instead of a plain zip bag.
