Someone joked on another thread about not being able to find a flag for the USSR. Actually, a lot of writers would qualify, because there are a lot of writers on this website where you have to choose a modern flag, when in fact they wrote as Soviet citizens, but in several languages, mostly Russian.
The Austro-Hungarian Empire must have had a flag, and many famous Modernists were still living in that multi-ethnic realm. Personally, without resorting to the Wiki or Google, I wouldn't have a clue what that flag looked like.
We can't blame Stewart for not getting rid of the all-green Libyan flag and replacing it with the stripy one with black in it. Because the fate of Libya still hangs in the balance.
Where, incidentally, does this little group of flag icons come from, and can flags be individually added or taken away? I'm always happy that the constituent flags of the UK and the one for Catalonia are present in the list. Because if someone is a Scottish or Catalan writer, it is nice to be able to mark that fact with a flag. I do think, however, that the Esperanto flag is used less often. Though the EU flag has its moments.
