How could anybody claim copyright on the British flag (around since 1707), or the French Tricouleur, which originated around the time of the Revolution (1789 edition - I know les grenouilles are rather partial to revolutions).   I assume that the Mexican flag dates back to independence, too, doesn't it?

Very nice idea, making these Australian flags.   Which one is Victoria's, by the way?   In the image at the top, NSW seems to get two.

I like the story of the Australian at a sporting event (possibly the Sydney Olympics).   A British sports fan is waving a Union Flag in front of him, so the Aussie taps him on the shoulder and says, "What's the matter, mate?   Couldn't you afford a whole one?"
