Hey Erik,
I tossed up a small logo that you can include on the site. I wasn't sure if you guys were opposed to displaying our logo or not, so what the heck... :)
http://mirrors.playboy.com/icons/playboy.gif
You can link it to http://www.playboyenterprises.com/ - I'm sure you'd likely not want to link to Playboy.com, since it has adult content; our corporate site does not.
Thanks again,
- Tim
