A repeating pattern of black railroad and steam locomotive imagery covers the white ground, featuring detailed technical drawings of trains, tracks, signals, and railway infrastructure rendered in crisp line work. The composition tiles symmetrically across the surface, creating a rhythmic, almost architectural quality that celebrates industrial heritage and mechanical 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.
