A detailed street map of Portland rendered in fine black lines against a clean white ground captures the intricate network of roads, neighborhoods, and the Willamette River winding through the city's center. The dense linework creates a sense of urban complexity and interconnection, with the river's curves providing organic counterpoint to the geometric grid of streets. 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.
