A black and white engraved map depicts the Great Lakes region and surrounding territories with fine linear detail, labeled place names, and decorative cartouches typical of 18th-century cartography. The composition fills the rectangular frame with intricate coastlines, waterways, and geographical features rendered in precise crosshatching and delicate line work. 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.
