A detailed street map of San Francisco rendered in dark gray linework against a clean white ground, with the city's distinctive peninsula shape and waterfront edges clearly delineated. The composition captures the urban grid and topography with precision, creating a technical yet meditative portrait of the city's layout. 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.
