There will be an offical photographer there, Russ Matthews, who is arkhamrefugee, and his work can be found at http://www.russmattphoto.com . I don't know if he might be willing to discuss publication rights in exchange for advertising or other compensation, but you might contact him and discuss it with him. He is the awesome photographer who took the picture in my default icon here, as well as a great friend. Please consider contacting him and seeing if you can work something out. It would be wonderful publicity for an event that supports a really great group of people. If you need further event information, contact featherynscale.
