The picture is from a series of postcards I bought in 1984. They show scenes from Blidworth Strike Centre in Nottingham in Autumn 1984 and they were sold in support of the miners' strike. Rediscovering the postcards yesterday I Googled Blidworth Strike Centre. According to the Retford Trader and Guardian it was re-opened in February this year as an air-conditioned gym and sports centre. How the world changes.
