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. At home in a bathroom, powder room, or any space celebrating functional design history. Printed on smooth gloss paper and made the moment you order it, then rolled into a tube and shipped ready to fill a wall. The same independent-artist artwork you'd frame, at poster scale and poster price.
