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 to order on smooth 100lb gloss paper, then rolled into a tube and shipped ready to pin, tape, or frame. Sized to fill a wall without filling the budget. The same independent-artist artwork you'd frame, at poster scale and poster price.
