I have a quick question regarding a t-shirt idea. It will consist of just a 5 letter phrase on the front--referring to a famous athlete(simply the first name, will be used in the phrase). I was wondering --is it illegal to put on the back of the shirt the athlete's last name and jersey number? I think I would need that person/ teams authorization before doing that correct? Will that team/player expect some proceeds each time its sold, eventhough it will not have the teams name or logo on the shirt--simply a phrase and that athletes last name and number on the back. I would greatly appreciate some advice on this topic. Please let me know and once again thanks again.
