Steampunk Constellation Mechanical Anatomy Poster

Vintage steampunk constellation anatomical atlas poster for [Sagittarius]. At the top, an ornate vintage ribbon banner features the title text "ANATOMIA [Sagittarius]". The background is aged, yellowed parchment manuscript paper with natural stains, subtle creases, and fine measurement markings. The central subject is the classic mythological figure of the constellation depicted as an anatomical cutaway, revealing internal structures made of precision brass gears, copper pipelines, mechanical clockwork, and metallic bone frameworks. Flanking the center are left and right side columns containing hand-drawn schematic diagrams, technical callouts, and annotation lines indicating mechanical functions. At the bottom are technical data tables, celestial coordinates, and observation notes. Rigorous hand-drawn scientific illustration style with fine line engraving. Color palette dominated by warm sepia, antique beige, and polished bronze with subtle high-contrast accents.
