I've been there. When I was in college I lived about 2 miles from Wrigley. As well as comics, I was into sportscards, and autographs. I remember I got a Mitch Williams autograph (the eccentric Cubs reliever, who later as a Phillie infamously gave up a homer to Joe Carter and a Blue Jays walk off World Series win). He too had a Mitch Williams autograph in a case (looked absolutely nothing like mine, that I just got from the real person). The one in the case looked like a 5 year old wrote the name on it, and he had some jacked up price on it. So I assumed he knew nothing of autographed sports cards, and never bought any thing from this store.
