Thanks to my bud Penshead for this. He snapped this pic when he was back in Pittsburgh for the opening 2 games at Consol Energy Center.
This is a pretty cool shirt, not gonna lie. I'm a fan of the simple generic shirts. It doesn't take much to add a Z to 'Yin Yang' with hypocycloids in place of the small circles. Rather than splashing PITTSBURGH FOOTBALL or something all over the place, this vendor took an easy concept that ended up both cleaner and more efficient than its tackier unlicensed brothers.
