Bog Door Blue and blue sky

      A set of raised tanks on a local farm, they're used by the farmer for storing the diesel for his tractors and other mechanised agricultural equipment.
      The eye-catching part is that they are painted in that well known heritage colour Norfolk Bog Door Blue, wonderful, who could resist a set of tanks as splendidly rendered as these are.
      We can quite easily visualise Constable, Turner or Cottman stopping in their tracks setting up their easel and paints in an absolute state of ecstasy at the sight of this little trio and then, of course, there's the blue sky.
