Vol. 22, issue 3 of Visual Culture in Britain includes an article by David Worrall, "The ‘Secret’ Life of William Blake’s Songs of Innocence And of Experience, Copy J: Anthony Blunt, The Rothschilds and M.i.5 In The Cold War":
This essay investigates M.I.5’s telephone tapping in 1969 of Anthony Blunt’s conversations about his gifting to Emma Rothschild of William Blake’s Songs of Innocence and of Experience (1795), Copy J. Blunt, Victor and Tess Rothschild had an agreement that Blunt would keep the book but bequeath it to Emma. M.I.5 suspected, wrongly, that the Rothschilds’ were extensions of the Cambridge Five spy ring. The essay draws on declassified documents in the National Archives.
David Worral is Professor Emiritus from Nottingham Trent University, and has written on and edited many works about Blake.
"The ‘Secret’ Life of William Blake’s Songs of Innocence And of Experience, Copy J: Anthony Blunt, The Rothschilds and M.i.5 In The Cold War" is available from Visual Culture in Britain (open access).
