A rust-red bull with black linear contours charges across a weathered cream and grey ground, its muscular form rendered with bold gestural lines that suggest ancient hand-stenciling techniques. The composition captures the raw energy of Paleolithic cave art, where earthy pigments and charcoal marks create a timeless image of animal power and primal artistic expression. 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.
