That is fascinating. Do you know the approximate date of the photos? Is your Grandad in one of them? The newspaper clipping would be very interesting.
I have shown the photos to Fiona Adams and Tony Thapar who are involved in running the Exchange. Fiona is a long-time resident of Moseley, founder member of the Moseley Society and she remembers in the early 1970s when the post office counter still looked much like it does in your picture. They have asked me to ask you if (a) you are ok with the photos being displayed on the wall of the newly renovated exchange, and (b) if so, could we get hi-resolution scans of them so that they print well at a larger size?
