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. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
