I'm part of a small circle of friends who meet at Cons and collect con sketches. We have linked our entire collections to our blog here: http://cranboyz.blogspot.com/
Here is a link to my CAF art gallery, if you head over to the blog you'll see links for several other gallery's. Hope you enjoy it as much as we do!

Currently I have two sketch books the first is an X-MEN themed, second is a MISC book so I can get anything else,
