Adam was such a prevalent signer there's probably not a lot of fake material out there. But there was a time period when secretarials were being sent from the Kazarian/Spencer agency, around 2002-2003. Same for Frank Gorshin. I doubt either guy even knew. Someone was having fun at the fans expense, pretending to be these stars. They were sending back handwritten notes, drawings, 8x10s signed with lengthy inscriptions.
