A historical nautical chart renders Nantucket in soft yellows and pale blues, with the distinctive curved coastline carefully delineated and marked with navigation circles and depth measurements. The composition balances precise cartographic detail with a muted, aged palette that evokes the authentic character of mid-twentieth century maritime documentation. 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.
