I believe that this 100% cotton Star Wars Expressions of Vader T-Shirt shows off one of the major problems that the Imperial Army had when dealing with the Dark Lord of the Sith...they would never know how he was feeling! I remember this one time when Steve from Engineering came in rather jovial in the morning. Vader, having just had an immensely rough night at the Space Catina, was hung over and had little use for loud, morning-loving wankers. Steve was never heard from again. Even with this shirt, which features multiple images of Vader in his different emotional states, it is still pretty hard to figure how exactly what he is feeling. Perhaps we should get him a mood ring?
