Cultural historian Mark Braude has published a book about Kiki de Montparnasse, the artist’s muse, who arrived in Paris in 1912 and first posed for Brancusi when she was just 16. She began haunting the Café de la Rotonde and met the circle of artists that included Modigliani.
Kiki Man Ray: Art, Love, and Rivalry in 1920s Paris is published by W.W. Norton & Company (2022). Here is a link.
