I wouldn't *think* so. Maybe if you had something signed by one of the recognizable guys (Cliffy B, Ken Levine, Hideo Kojima, etc.) - but even then, I would think you would need some kind of certificate of authenticity for it to carry any real value. I wouldn't think that signatures by guys on a dev team that no one really knows would carry much monetary value. Would be a cool thing to own, sure, but as far as selling it for big money I kinda doubt it.
