Four Americans in Paris: The Collections of Gertrude Stein and Her Family by Irene Gordon (1970)
LibraryThing member AlexTheHunn
This slim volume is the companion piece to an exhibition held in 1970. Aside from Geertrude's literary merits, the Steins ammassed an astounding collection of paintings by impressionists that any museum would be proud to possess.
"The five essays in this book characterize each of the Steins and discuss the artistic preferences of each one of them and others in their circle."
