A golden-brown rainbow trout floats against a warm cream background, rendered in detailed naturalistic style with precise scales and fin work. The fish is positioned vertically in profile, its body glowing with amber and yellow tones that evoke both scientific illustration and vintage natural history 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.
