From a current eBay auction:

A friend on my uncles was a trainer for the Texas Rangers. He gave him this mesh jersey in 1995 for a Christmas gift. It has the 125th Anniversary Patch. It's made by Majestic, and is a size 46. On the back is the number 14. I'm sure with a little research someone can find out who it belonged to. It is signed by George Bush on the number '4' . The signature is a little smeared. I believe this was the last year that Bush owned the team. I'm sure with very little effort the signature can be removed.
