Anyone ever done a signing where Under Armour is the promoter? I'm going to this (sorry guys, full on the 50/50) but wondering if they won't let him sign outside items. It would suck driving from Houston to Dallas and he doesn't sign them. I called the store and they're not even sure, they said it's being put on by Under Armour, they assumed he would sign since it's for 1 1/2 hours. But I'm just wondering if Under Armour will only have him sign their items.
