Ask me on my discussion page if you need this image relicensed.

I will find a way to bust you for copyright infringement if you misuse this image.[1][2][3]

I am more than happy to multilicense it for combination with other free content works but I'm not doing that here because I don't want Wikipedians improving it under the GFDL, which I feel imposes unnecessary burdens on printing images.
