A detailed street map of Portland, Maine rendered in fine black linework against a clean white ground, with the city's distinctive peninsular geography and surrounding waterways clearly articulated. The composition balances intricate urban detail with generous negative space, creating a precise yet meditative cartographic portrait. 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.
