Guy DeWolf outgoing help

Me and my mom always talk about the old guy, 87, who runs the coin, stamp, autograph, etc. shop Williamsburg. It's a long story, but basically I googled him and an IMDB profile popped up. I was instantly curious. Could this be the same guy? I did some research and found out that that man had one line in a 1948 movie titled The Cockeyed Miracle. It turned out his mother was the screen writer. Naturally, I saw this as an autograph opportunity. Anyways, I got my items signed about a month and a half ago, and someone on facebook was interested in an 8 by 10 movie poster signed by him, so I offered to get one signed for him.
