A detailed street map of Chicago rendered in fine black linework shows the city's grid layout and waterfront edge against a clean white ground. The precision cartography captures the dense urban fabric with methodical clarity, creating an intricate pattern that reads as both geographic document and abstract 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.
