"Engraving By Solange De Bièvre, Portrait Of Her Father."
Solange de Bièvre was a student of André Lhote and influenced by Dunoyer de Segonsac. She led a bohemian life as an artist in the Latin Quarter (rue Visconti), ending her days in poverty in a retirement home (https://www.ruevisconti.com/ImmeubleNoParNo/20.html). The last photo shows a photograph by Ambroise Vollard dedicated to Solange de Bièvre. The engraving is unsigned and annotated on the back: Solange de Bièvre, her father.
