A grayscale map of Boston presents the city's dense urban fabric in fine detail, with streets and neighborhoods rendered in intricate linework against white water and harbor areas. The monochromatic composition creates a striking contrast between the intricately textured land and the open space of the coastline, offering a bird's-eye view of the city's distinctive geography. 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.
