I believe he did show a pic of himself awhile back (couple years maybe?) along with something he was doing for a library. I seem to remember seeing a picture of him sitting at a table with a friend.
Unless I'm remembering this wrong, which is entirely probable.
Grazie's has always been polite, even courteous to y'all, so do not pressure him about showing his face. And do not be so sure that you could even stand to watch the mighty countenance of that man. Or his Mickey Mouse cap.
Grazie is a very talented "artiste"! He applies his creative insight to his vegas editing! A plus for all. Of course, his mice work force used to be charge in cooling the computer hardware with his heavy editing and rendering, but then he had put his foot down, they were playing too much with the wiring! ;-)
