A commuter train suspended on elevated steel tracks dominates this black and white photograph of Chicago's iconic Loop infrastructure, captured from directly below to emphasize the geometric complexity of the structure and the urban canyon it creates. The composition layers the train car's curved metal body against the sharp angles of surrounding buildings and support beams, creating a dense, architectural study in contrast and industrial geometry. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
