There are a couple of concerns with this alleged GU 1988 Yankees home Don Mattingly which make me doubt it's advertised status.

First, the NIC/year/set tag does not look consistent with the font introduced by Wilson in 1988, and looks to be a poor attempt at replicating the pre-1988 embroidery font for such a tag. Also, the jersey is a size 44...Donnie Baseball wore 42s at the time.
