Weird, nearly all of his jerseys appear to be autographed.
What do you mean by “authentic”?
I did find this one on Ebay, but the seller is a company in the Philippines, so buyer beware.
You can customize a jersey and add the name and number. Don’t know how much the uni has changed since he played, but that might be your best bet, as it’s from NFL shop and about as authentic as you can get.
E-bay didn’t help. By “authentic”, I mean a jersey that is, optimally, the same as he wore when he played. Perhaps they were sold at the time. If not available, then one that has a replica design. I also found it odd that the only “authenic” ones that seem readily available are all “autographed”.
I may have to go with that one. You’d think that true authentics would be a bit more prevalent considering that he was a starting receiver from one of the great dynasties in NFL history, a 4-time Super Bowl champion, a hall-of-famer…and my favorite player of all time.
