An old joke that just didn’t work with the usual characters.
I know some people won’t get it, and all I will say to help you along is: Please notice what Sweden and Finland looks like together without Norway. ;)
That was actually what early euros looked like because Norway isn't in the EU.
Åland got it's own flag because he is a fairly big character in the usual comics.
