I should have stated that the Gibson was purchased around 1993 or so. His signature has definitely started to shake on his newer stuff with his advancing age. Also, I bought the Gibson at a Sam's Club of all places. They had a bunch of boxes with packs in them, and each box also contained an autographed baseball. The thing was, you could see the ball so you got to pick who you wanted!
The Thomas is the one I'm really not sure about. My dad bought it for me on my 14th birthday, I'm pretty sure. So around 1992 I believe. Comiskey opened in '91, so I would say it was either '91 or '92. I've noticed his newer signature is a little different than this one, but I've seen magazines with a very similar signature to mine slabbed with a PSA/DNA sticker.
only thing with the Thomas that bothers me is that it is rather bold...most of the Frankers I've seen he tends to be a light sig so to speak...especially around the edges...if you know what I'm saying.
