I certainly would not disagree with you there, Lyn, Birmingham is somewhere to be proud of, it was the first manufacturing city in the world - and not everyone realises that. I don't think I would want the postcards on my wall, but I still think they were produced a bit tongue-in-cheek. I also think they were a bit unkind. Bristol was built on slavery and sugar, but were postcards produced of that? I suspect not.
I think the worst thing about it is the realisation that our ancestors had to breathe in this heavy smoke, no wonder a lot of them had chest problems. People in London still think Birmingham is dirty - I was at a meeting in about 2004 with some councillors, and one of them spoke of a function he had been to in London, just the year before, where Anna Ford (the ex-newsreader) in a speech, spoke about 'dirty Birmingham' - what was once true is probably always true to anyone south of Watford, more is the pity.
