National Gallery of Canada, purchased from Robert M. Light and Artemis through Eugene V. Thaw, New York, NY 
 According to the invoice, art collector and curator Henry P. McIlhenny acquired the work from Valentine Dudensing on August 29, 1933 [copy of invoice from Dudensing, NGC, curatorial files, Henry P. McIlhenny Papers, Philadelphia Museum of Art, Box 81, folder 2, Dudensing, Valentine]. In his correspondence, McIlhenny recalls the sale: "...for myself I acquired an interesting surréaliste work by Salvador Dalí. The title is 'Gala et l'Angelus de Millet précédant immédiatement la venue des anamorphes coniques.' Its meaning is incomprehensible, but it is beautifully painted, like a primitive in its minuteness. Tiny, and in a black velvet box frame it's very striking and fascinating." Rishel, Joseph P. “The Henry P. McIlhenny Collection, An Illustrated History.” (Philadelphia, PA: Philadelphia Museum of Art, 1987), p. 38].
 According to a note from Gyde V. Shepherd, former assistant director, to curator Brydon Smith, Robert M. Light and Artemis owned the painting jointly [memo dated July 4, 1975, NGC, curatorial files].
 Invoice dated July 7, 1975 [NGC, curatorial files]. Legal date for acquisition, August 7, 1975.
