I don't see a single copyright infringement on this. UNC can't copyright 2 colors, an athletic type font, a jersey drawing and a stock photo of a crowd. Maybe the diamond pattern on the side of the jersey. He'd have to have used a licensed logo here to really have some problems I think. It's like when you see Jordan wearing a red and black number 23 jersey on a box of Wheaties... they obviously didn't pay the license fees for the NBA and the Chicago Bulls.
This is all speculation here but John dodged the copyrights pretty well on this I think, well done.
Nice print, I need to do one for them.
