A cream and tan cartographic rendering plots the topography and waterways of Yellowstone National Park with fine linework, contour markings, and pale blue watercolor indicating rivers and thermal features. The composition carries the measured precision and aged patina of a nineteenth-century survey map, with its grid lines, inset detail boxes, and handwritten typography suggesting historical documentation of explored terrain. 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.
