This was my parents and is an authentic 1981 Tour 3/4 Sleeve shirt. I’d kill to keep it but it’s too small. The dimensions are in the photos and remember that the bottom of the shirt tapers a bit.

The only condition issue to point out is the YELLOW STAIN below the tongue near the “TM”. (last photo). I didn’t wash it or try to remove it as I didn’t want to mess with a shirt that’s been stored in a drawer for decades. Any questions or additional photos let me know. Thanks.
