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. 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.
