A vintage patent drawing depicts two tapered baseball bats rendered in precise technical lines, flanked by detailed cross-section diagrams showing the bat's construction from multiple angles. The sepia-toned paper and formal patent notation create an antiquarian aesthetic that celebrates the engineering precision underlying America's pastime. 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.
