Bradbury, Kirsten (1999). Essential Dalí. Dempsey Parr. ISBN978-1-84084-509-9. It includes the first appearance of what is perhaps his most enduring image: the 'soft watch'.
Salvador Dali.The Dali Dimension: Decoding the Mind of a Genius(DVD).Media 3.14-TVC-FGSD-IRL-AVRO."Surprisingly, Dalí said that his soft watches were not inspired by the theory of relativity, but by the surrealist perception of a Camembert cheese melting in the sun.
