Can't find a Software Center Badge?

view story

http://askubuntu.com – I just published my game "Plush" to the software center, and I want to have a badge on my website that links to the web listing, but based on my searches, software center doesn't seem to have a "Badge" (for example, here's google play's: http://developer.android.com/distribute/googleplay/promote/badges.html ) Am I just missing it? If there really isn't one, I guess I just use an Ubuntu logo? (HowTos)
