Octopus Anatomical Marine Study Vintage Natural History Illustration Poster

This 19th-century marine study presents two octopus specimens – one in deep rose-brown, one pale with rust-red shading – surrounded by numbered anatomical diagrams of suckers, arms, and internal structures. The scientific-plate aesthetic, with fine stipple shading and hand lettering, gives it a distinctive steampunk-meets-natural-history character. A conversation piece for ocean lovers, libraries, and collectors of antique scientific illustration.
