body: I'm posting here, because I'd like to do something but I'm concerned about the legal aspect of it.
  
  
  A lot of websites propose to sell t-shirts, goodies, etc. based on your designs. I'd like to sell t-shirts with the direwolve emblem of the "House Stark" in Game of Thrones, and of course, I've been immediately asking myself if HBO which produces the serie actually had some copyright on that emblem. I've searched a lot, but didn't found anything.
  
  
  I also saw this video, where a girl who used a simple sentence from the serie was threatened to be sued, so you get my point : <http://www.dailymail.co.uk/news/article-4032504/Game-Thrones-threatens-SUE-autistic-schoolgirl-13-girl-used-phrase-winter-coming-artwork-competition.html>
  
  
  Of course I do not intend to use some copyrighted content, so that's why I'm asking, but how to know what can be used freely ? what sentence ? what sigil ? For example can a sentence as "The North Remembers" be copyrighted if there's no image under it ?
  
  
  Thanks for all your legal advices !
