Lady Iya Abdy, the dedicatee of "Photoheliograph," was a friend of Manuel Ortiz, a young Spanish painter with whom Caresse was having an affair. In a passage for November 7, 1927, in Shadows of the Sun, Crosby records meeting her among a group of painters. He called her "The Lady of the Music Shop (Lady A)" and added: "she is strange and she wears strange hats from Reboux and I liked her."
