This Seinfeld t-shirt features an image of George Costanza giving a thumbs up. The shirt reads It's A Festivus Miracle! In the Seinfeld season nine episode titled "The Strike", Kramer learned of Frank Costanza's made up holiday named Festivus. With this holiday, Frank put up an aluminum pole instead of a Christmas tree, he had his Airing of Grievances where he told everyone what problems he had with them, and the Festivus celebration wasn't over until the Feats of Strength where George had to pin Frank to the floor. For any fan of Seinfeld, this Festivus Miracle t-shirt is a must have!
