The librarian writes:
The Prospectus has been bound with a type of yarn or twine. It originally contained two more pages as well as an outer wrapper, but these are damaged beyond repair and cannot be deciphered or even handled.
One curiosity about this Prospectus is that it bears striking similarities to some other school brochures of the time, for instance one (inexplicably found in the same box as this) from the Friends School Saffron Walden. It is possible that the schools engaged the same person or firm to design their brochures, though no credit is given in any Prospectus for design, copywriting, or photography.
