- NLW MS 21980C.
Seventeen letters and one note, 1926-1952, from Augustus John, ten of them to Sean O'Casey (ff. 2-13) and the remainder to the journalist George Bilainkin. Those to Sean O'Casey contain mainly personal news, but refer also to O'Casey's work and to John's designs for the set of 'The Silver Tassie', staged in 1929 (ff. 4 verso, 6, 7). Extracts from them were published in Eileen O'Casey, Sean (London, 1971). The letters to Bilainkin (ff. 14-20) refer mainly to the latter's articles on John.
John, Augustus, 1878-1961
