I received my autograph from Mr. Moroder, the pioneer of "Italo Disco" and Electronic Music. I sent an e-mail at https://www.giorgiomoroder.com via the "CONTACT" section with my postal address and i received a small postcard from St. Ulrich Ortisei, Italy. Thanks Mr. Moroder!
Pretty sure that's authentic. The card is exactly the same as the one I received after exchanging emails with his wife requesting an autograph. You can see mine here: http://www.surfmypictures.com/image/55d ... use1x.html The autographs are different enough that it's definitely not an autopen.
