Why is this so special? If you were looking for an average 1990s major league pitcher, John Doherty fits the bill pretty well. In five seasons as a starter and reliever, he had a 32-31 record with a 4.87 ERA and an adjusted ERA+ of 91.
This is the only signed 1st Day Edition Stadium Club card in my collection - I've never gotten any of the others I own signed. For those who don't remember collecting Stadium Club, the 1st Day Edition cards turned up at a rate of about one per box. Aside from the little rainbow foil stamp, there's no difference between the 1st Day Edition cards and the regular ones. Yet I was fascinated by them in 1993 and 1994, and even now I will buy them when I run across them.
Though some might deduct points for the printed initials, I rather like Doherty's autograph.
I'm only putting autograph-related links in this blogroll. However, if you have a blog or a collector site not specifically about autographs, but with an autograph page or an "autograph" label on your blog posts, I'll put that link here.
