I bought it from the team so it has a team LOA, but I'm pretty confident that I've photomatched it to three games. Luckily it has a very distinctive feature. Here is a picture of the stitching of the bat knob on the Percival jersey...
and here is how the stitching is supposed to look...
Based on this, I have been able to rule many photos out, but I've also found photos from three games that look very promising.
This is a UPI photo from the last game of the season (9/30/07) in which the stitching appears thicker than it's supposed to be.
This is a photo from a Cardinals-Cubs game on 9/18/07. I think this one is the most promising. I've ordered it in an 11x14 so I should be getting that soon, and hopefully I will be able to confirm it.
There's also an AP photo from the 9/30/07 game in which he appears to be wearing the jersey, but without posting the high resolution photo, which I obviously can't do on here, it's really not all that noticeable.
For comparisons sake, here is a photo from 7-18-07 in which he is obviously not wearing my jersey.
