No, because as you can see, the tshirts are made by MARVEL (look at the back of the neck), not some joe blow company. These are probably going to be all over the place with sports paraphernalia...
Geez people use your head. This is a great tactic for both parties. Marvel gets their brand name characters out there, and the kids and nerdy grownups, like myself, will go and bye these which will help promote the Bombers.
