Unisex Van Halen concert tee

Got this at the Van Halen concert that was at the Forum in Los Angeles years ago. I can’t remember the year, but on the way home, I learned that the real Henry Hill had just died. Anyway, I was in a VIP section and this came in the VIP bag. I only wore it to sleep in. No clue what that little stain is on the front. I guess what I’m saying is, buy my cool pajamas.
