I used to buy/sell/collect postcards many years ago when people were literally throwing them out as rubbish. I had about 10,000 cards mainly from the Edwardian and early George V eras. Many were photographs of street scenes, shops, seaside resorts etc. I especially treasured the local ones which were close to where I lived and often used to try to find the exact spot from where they had been photographed. Sometimes I was impressed at how little things had changed, but, sadly, most times, how the actual scene was almost unrecognisable from the postcard.
As regards cinemas, just before lockdown, a few friends and I were listing all the local cinemas we had been to in our youth. The list came to over 30, but, sadly, only one remains, and it is now an abandoned building.
