Thanks to @jonwitout for ensuring that I saw this one:
Mass Communications Academic, @MMUBS. British Home Front Propaganda posters as researched for a PhD completed 2004. In 1997, unwittingly wrote the first history of the Keep Calm and Carry On poster, which she now follows with interest.
No worries, I have also seen a few Star Wars and Doctor Who themed ‘Keep Calm’ posters/mugs.
