“Ingres' Violin” shows the back of the model Kiki de Montparnasse (1901-1953), in a position that refers to paintings by Jean-Auguste Dominique Ingrés (1780 - 1867), a painter who was also a music lover; for this reason, Man Ray deepened the reference by painting with ink the two efes or acoustic openings of the violin on Kiki's back (on the photograph).
