he's got all these designs on display, people go up and tell em what design, what color shirt and he presses em there on the spot. I would guess that a large percentage of his designs contain blatant copyright protect logos like NFL logos, comic book logos/designs, etc.
While it's true I guess he could have a legitimate licensing agreements in place, I know for a fact (i read it once on the internet...) that doing business with the NFL alone is a minimum of like $50,000. Has anyone else ever seen anyone setup shop like this?
