I know about the North-German Confederation, but in my opinion the comic would be better if I skipped that. At least it exicted less then 4 years whereafter only Bavaria, Baden, Würtemberg and Southern-Hessia joined and the German Empire was proclaimed. I think it was not necessary to give die norddeutsche Bund a role (at least the conf. and empire had the same flag ).
i have a good idea for a countryball comic, since i cant draw, its about sweden, here in sweden where i live, its common to see a small triangle flag of sweden around the country, kinda like this on but twice as long sideways http://www.1000flags.co.uk/sweden-triangular-flag-bunting---20m-long---54-flags-52901-p.asp. only its alot more common seeing them with a flag that looks like ukraines, have russia visit sweden and see thise ukraine looking triangel flag, you decide the end
