Dear John,
Thanks for your reply. I was clearly not precise enough when I wrote about J. Guggenheim's photographs - they are photographs produced at his shop on The High in Oxford. They'll be photos of his clients; I doubt that any are of his family. I am interested in his 'eye' - the way he photographed. He's a relatively early photographer. Do you know that there are some of his photographs in the National Portrait Gallery in London?
