A technical patent diagram of football pants rendered in white linework against a black chalkboard ground, showing front and back views with detailed annotations of pockets, padding, and construction seams. The composition captures the precision and instructional clarity of vintage patent illustrations, executed with the hand-drawn quality of chalk on slate. 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.
