My favourite painting is ‘The Fighting Temeraire’ by Turner whose home is the National Gallery. It depicts a scene of one of the last gun ships from the Battle of Trafalgar being towed off for scrap by a paddle steamer. To me it symbolises transformation in moving from one stage to another. I find it very powerful and moving. Anyway, managed to duck out at lunch today to pop into the gallery and take this pic with the new £20 note (in front of some very patient tourists!) #transformation
