A detailed street map of Chicago rendered in white lines against a black background, with the grid of neighborhoods and thoroughfares creating an intricate urban geometry. Lake Michigan forms a dark void along the eastern edge, emphasizing the city's relationship to the water and the cartographic precision of the composition. 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.
