I think Richard and Stephen would be too big for these events. Richard has done events so he's a possibility for one of the LFCC or Collectormania shows, but I don't think Stephen has ever done one and I don't think he ever will unless circumstances dictate that he needs to. I jokingly asked one of his nephews once if his uncle would ever do a signing event and he laughed and said no. Things do change though so you never know, but if they did ever manage it, I think he'd be an LFCC guest.
