Whatever it is, it’s cut off the whole town. They’re trapped! Show you’re a fan, and living outside the dome, with the Under the Dome Trapped Poster. The 11 x17 in. poster features the bloody handprint left on the dome from the first episode of Under The Dome, the show based on Stephen King’s novel. Be grateful your wall isn’t that of a dome when you put up this poster, which comes in a hard plastic sleeve with a hook, ready to hang.
