A detailed naturalistic illustration displays dozens of freshwater fish species rendered in precise brown ink line work against a cream background. The fish swim in organized yet dynamic scattered composition, each rendered with careful anatomical detail including scales, fins, and fishing hooks, creating a sophisticated cabinet of curiosities effect. 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.
