Like many other films and television series around this time of the year, the NBC spy show Chuck figured a poster would be a great way to commemorate Comic-Con.  But the marketing department decided to mix things up a bit.  The show designed a War Games-inspired poster internally, then set up a competition where fans could submit their own works of art.  You can check out the official poster and two different fan posters after the jump.
