Thanks to the wonders of the infinite canvas, here is the complete quiz for your delectation, a mere 14 hours later than intended. Simply let us know in the comments what each string of flags represents, and earn the admiration and respect of some people on the internet. The gentleman's agreement mentioned in this morning's post still stands.

If you're still not satisfied will all this quizzing and need some more, Uncle5000 has a quiz on today, too.
