A sketchbook of Marc Chagall's drawings and watercolors that's never been published is going on the auction block in New York in June.
Many of the 85 pages are devoted to Chagall's beloved wife, Bella, following her death in 1944.
Sotheby's says it's estimated to bring $600,000 to $900,000 on June 17. It's currently in a private European collection.
It'll be shown in Paris May 16-17.
The auction house describes it as a virtual catalog of Chagall's colorful and moving iconography. It says none of his sketchbooks have ever appeared at auction or contain such range of imagery.
The book originally belonged to Bella Chagall, who filled the first eight pages with her Yiddish translations of French poetry. Chagall used it after her death, from the 1940s to the 1960s.
