A gridded street map of Chicago unfolds in white lines against a deep blue background, rendered in the clean, technical style of architectural blueprints. The composition captures the city's orthogonal layout and major thoroughfares with precision, creating a sense of order and urban structure while maintaining the understated elegance of vintage planning documents. 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.
