Russian painter (1866–1924) remembered for the exotic, richly colored sets and costumes that he designed for the Ballets Russes. ALS in French, two pages, 4.5 x 7, no date. Letter to Robert de Montesquiou. In part (translated): “Madame [Ida] Rubinstein has alerted me that you had attempted to write me two letters…but these letters never reached me, because I have not set foot in my studio, having obtained another on Rue Falguiere!…I asked Reynaldo Hahn where you were…He told me you were in the country and that you’d be returning in the autumn.” Pages affixed to each other with tape to the left border. In very good condition, with intersecting folds, overall creasing and wrinkling, and a few trivial spots of foxing. RR Auction COA.
