A golden-line street map of San Diego traces the city's network of roads and neighborhoods across a clean white ground, rendered in warm mustard tones that evoke both vintage cartography and contemporary minimalism. The composition captures the organic sprawl of the urban landscape, from coastal curves to inland grid patterns, with precise linework that transforms geography into an elegant, readable composition. 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.
