A red steel elevated train trestle spans across the frame, its geometric lattice work creating strong diagonal lines against a backdrop of towering rectangular buildings in cream and pale gray. The composition captures the graphic contrast between the industrial infrastructure of mid-century Chicago and its modernist skyscrapers, with a commuter train visible on the tracks above, rendered in cool blues and whites. 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.
