Der Mensch als Industriepalast (Man as Industrial Palace)
Stuttgart, 1926. Chromolithograph. National Library of Medicine.
"Kahn’s modernist visualization of the digestive and respiratory system as "industrial palace," really a chemical plant, was conceived in a period when the German chemical industry was the world’s most advanced."
From U.S. National Library of Medicine: Dream Anatomy Exhibition
