The style, composition, and subject strongly recall “Freikörperkultur” — the German naturist movement that celebrated nudity, sunlight, and physical health as part of natural living. The Freikörperkultur (Free Body Culture) emerged in Germany after World War I and promoted body freedom, hygiene, and the unity of mind, body, and nature.The photo’s modernist composition (strong silhouettes, rhythmic repetition, clear geometry) fits the Neue Sachlichkeit and Bauhaus visual aesthetics of the interwar years.
