'Udnie – I see Again in Memory my Dear Udnie' is no more the portrait of a young girl than 'Edtaonisl' [counterpart of his work 'Udnie'] is the image of a prelate, as we ordinarily conceive of them. They are [both] memories of America, evocations of over there which, subtly set down like musical chords, become representative of an idea, a nostalgia, a fleeting impression.
