There are in fact two sets of post cards, the first is the one shown containing 12 interior shots, the second contained 12 esterior shots of the buildings and grounds.
The post cards were taken from a set of 28 photographs taken about 1911, these were produced in booklet form and there are quite a few copies of this still about.
The post cards were produced for pupils to buy and write home to their parents (the school was a boarding school at that time).
Most of the pictures, and other old pictures of the school are here
I would be very interested in seeing the pictures from the 1980s which you have.
_Ste_: Yes, the buildings still exist and are still in use by the school.
