A topographic map of Lake Winnipesaukee rendered in soft yellows, pale greens, and light blues shows the lake's intricate shoreline surrounded by roads and regional geography. The vintage cartographic style employs fine linework and delicate color gradation to convey both water depth and land elevation with understated precision. 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.
