An autograph letter signed, New York, January 13, 1948, by the Russian-born painter, set designer, landscape and portrait artist. Addressed to the author and book dealer Herbert Bittner, who wrote books on Kollwitz and Grosz, among others. In full: "Thank you ever so much for the kind note you wrote to me about my exhibition - I was very touched. I encIose herewith a check for $15 on account of my debts for the books I took before X-mas. I had a letter from Miss Edith Sitwell the well known poet of England, with thanks and admiration for the work you have done. She had apparently never received the copy sent to her in Sept. (Miss Edith Sitwell F.R.S.T. Renishaw Hall / Renishaw near Sheffield, Herbyshire, England). Neither has Mr. Kenneth Clark [British author, museum director, broadcaster, and one of the best-known art historians of his generation], nor my sister! The books were sent by Lincoln [Lincoln Kirstein - American writer, impresario, art connoisseur who authored a book on Tchelitchew and was the subject of one of the artist's most famous paintings], as he told me. Could you, kindly, look up the receipts and find if those names were there? If not, I will ask Lincoln for his N. annd dates of the receipts. I include also some stamps for your secretary...Sincerely yours, P. Tchelitchew."
