In an old box I found a Photo Technik International from 1990. It has an article on the work by Sue Packer. She made some beautiful black and white portraits of the girls at "The Cheltenham Ladies' College". The series has also been published in a book, but it seems to be out of print. It would even be better to see the original prints.
Personal note: For me, it is very funny to realize that I stayed several times in the hotel on Parabola Road in Cheltenham, just across the road of this traditional English college.
