A detailed street map of Chicago rendered in fine black linework shows the city's grid layout and waterfront edge against a clean white ground. The precision cartography captures the dense urban fabric with methodical clarity, creating an intricate pattern that reads as both geographic document and abstract composition. 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.
