I agree with the others. Looks like a typical Slash signature. Its remarkable that he still signs TTM to the fans. And they are authentic in my opinion. It takes a while to get them back, and sometimes you dont, but i have gotten 3 from Slash from writing him at his fan mail address. I kept hoping he would do the skull and bones doodle but alas, i think the days of him doing that for random fans are over with. I think you have to be special to get that nowadays
