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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
