qaleghqa'neS!

I'm wondering whether there are any canon-friendly Klingon banners or flags that I can fly in public that are not the very, very nazi looking red-white-black one.

I live in Germany and the alternative might even put me into legal trouble based on whether the judge is having a good day or not, and I just don't want to take any chances or arouse any undue attention from neighbors who don't know anything about Star Trek.

I know there's the green-yellow-red emblem that's much better, but the only full flags that I can see are butt-ugly, non-rectangular green banners from DS9.

There's also this really cool looking one from Star Trek VI apparently, but I don't know what the canon implications are or where to get one: Klingon Flag

Any ideas?
