A historical map of Boston from 1902 depicts the city's street grid, neighborhoods, and waterways in warm ochres, tans, and muted reds, with the Charles River winding through the composition in soft gray-blue. The cartography captures the urban layout with precise linework and period typography, evoking the methodical craft of early twentieth-century mapmaking. 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.
