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. Bound with 52 pages of 70lb paper, lined or unlined, behind an anti-scuff matte cover with wraparound artwork, made to order. Notes and sketches kept behind an independent artist's work, not a plain composition cover.
