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 on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
