A vintage patent diagram for a toilet seat fixture renders the technical innovation in detailed line drawings against a weathered cream and tan background. The composition arranges four numbered figures showing different views and cross-sections of the mechanism, complete with handwritten annotations and official patent markings dated April 9, 1929. 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.
