From the notes of Dr. Catherine Perry: On the first card, Noailles thanks a man for quoting her speech at the Academy of Belgium in his article. So this visit card dates to after 21 January 1922, when she was received in the Academy. In pencil, a later hand has written "Vct de Guichen", probably referring to Eugène, Vicomte de Guichen (1869-1938), a historical writer and member of the Académie Française. The recipient of the second card is probably a publisher or an editor, because Noailles counts on him to check that there are no frightening typos, as she knows that she is not very legible. This card is impossible to date, but from the handwriting is must be in the 1920s.
