Tim graciously forwarded the picture. It's Joe Jonas backstage at a meet and greet. Tim says he also wore the t-shirt on stage but there were multiple costume changes so it was temporary. I know the picture, though I've never seen the shirt. It's Hell (on our left) standing beside a picture on the wall of a naked female torso that's tied up in rope. No wonder Joe wore a shirt over it. Does anyone recognize the other image on the shirt?
