I'm participating in BookNet Canada's PubFight this year.
My fictitious publishing company is called Xander House - "Books worth getting excited about!"
Here's the avatar I've created for it -- based on pictures of my son when he was a baby during various moments of "attacking the camera" -- I created a blog post about this a loooong time ago. (October 2005 to be exact)
More info on this exciting "fantasy publishing" game to come.
