I've cleaned for you this amazing salt print photo of London, taken nearly 200-years ago from Blackfriars Bridge by Henry Cundell. It was taken in 1844 and is the earliest photo of St Paul's and one of the earliest of London itself. Taken only a couple of months after the publication of 'A Christmas Carol' by Charles Dickens, this is an incredible and rare oppotunity to see the real Dickensian London, with St Pauls shrouded and obscured by the thick, smoggy air of old London town. A truly remarkable window through time!
