Chess pieces from historical patent drawings appear in technical line-art style across a black background, each piece labeled with dates and measurement annotations in the manner of official blueprints. The white linework renders a king, queen, bishops, knights, rooks, and pawns with precise geometric detail, capturing the formal elegance of game artwork through the lens of industrial 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.
