A detailed topographic map rendered in black ink and blue watercolor depicts the Great Lakes region with its intricate shorelines, elevation contours, and geographic features spread across the composition. The muted palette and precise cartographic line work convey both scientific accuracy and a contemplative sense of vast natural geography. 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.
