If you look hard enough online (as in… google “T-Shirts”), you can find sites that sell unlicensed and unofficial t-shirts. These T-shirts feature designs created by fans and basically only are allowed to exist because they are fairly small-scale operations- the equivalent of those random guys outside of a stadium- and no company is willing to sue them to oblivion because of the bad PR that would result from going after people who in essence are their biggest fans would be… bad. In addition, a lot (but certainly nowhere near all) of the t-shirts don’t technically break any laws and don’t actually use anything trademarked or copyrighted.
So, what type of stuff are we talking about? (go below the jump to see the rest of this)
