Nice to see the Cecil Beaton exhibition !
Steven Runciman, who I only knew (slightly) as a Grand Old Man was photographed upside down at Wilsford in 1927 when he was already a Fellow of Trinity:-

He had been photographed earlier holding a tulip in 1922:-

And Dadie Rylands as the Duchess of Malfi:-

Have you read Minoo Dinshaw’s biography of Runciman ? Very good.
Yes, I certainly have. Masterly. Charles
