(Probably Unworn) Vintage Lou Gehrig USPS Stamp Shirt

*Vintage sizing. May be smaller than a modern XL. See measurements.* Vintage from 1989, bought new. I'm the original owner. Commemorates the postal service’s Lou Gehrig stamp and 150 years of baseball in the U.S. I don't think I ever wore this (I don't like white t-shirts, but I got this anyway because I was/am a Gehrig fan), but there are two storage stain spots on the back (see last photo). It was stored in a drawer for all these years in a climate-controlled home (not in the attic or basement). One spot is nearly gone after I spot treated it (followed by a full wash), so it’s hard to see. The other lightened after spot treating, so it’s possible that it can be lightened further with more treatment (I'm not guaranteeing that; just saying that it might be worth trying to treat it more). Screen Stars Best label. Midweight fabric, maybe on the lighter end of midweight. Size XL 50% cotton/50% polyester Pit to pit: 22. 5” HPS length: 29.5” SFPF home
