Join was a piece of propaganda in the form of a poster, a collaborative effort by Coba Dunivee and the Galactic Empire's Commission for the Preservation of the New Order. The artwork showcased a stormtrooper gazing forward as two TIE fighters soared through a starry expanse; the phrase "Join the Imperial Army" was displayed at the bottom, with the letter "O" designed to mimic the appearance of the Imperial crest.
A different version of the poster was produced, presenting "Join the Imperial Army" using the Aurebesh alphabet.
The rebel artist Sabine Wren vandalized Join by adding graffiti. The term "Join" was covered up by the word "ReBeLS." In the lower right corner, Wren's signature starbird symbol was present in blue, and a red "X" was drawn over the stormtrooper's helmet.
