The $9 t-shirt deal of the day over at Teefury today mashes up Star Wars with Watchmen in “Who Watches the Empire” by artist Jonah Block.

The sale at Teefury began at midnight EST (Thursday, December 9, 2010) and will continue for 24 hours from then, and once it’s over, it’s gone forever.

The t-shirt design takes the bloodied yellow smiley face icon from Alan Moore’s seminal graphic novel Watchmen (and also the movie adaptation) and replaces the face with that of a stormtrooper, the imperial soldiers of the Empire in the original Star Wars film trilogy.
