Surrealism originated in the late 1910s and 1920s in Paris as an artistic movement that sought to release creativity from the unconscious mind. Key historical surrealist artists included Salvador Dali, Rene Magritte, Max Ernst, and Man Ray. Their works featured disjointed and dreamlike scenes using techniques like cutouts and unusual juxtapositions. Contemporary surrealism is commonly found in advertising to create new perceptions of products and services through techniques like photo manipulation, digital enhancement, and optical illusions that relate to dreams and fantasy. Companies like WWF have used surreal advertising to powerfully represent global issues.
