It looks like Lucasfilm is mailing a set of six Imperial propaganda postcards to 2500 fans around the world on Wednesday. Here are some of the images...
Some of the sites that got the cards are IGN, Empire, Mashable, The Force, Omelete and ET Online.
The Official StarWars site has posted the following description:
The Empire's propaganda machine is in full effect.
Six pieces of Star Wars Rebels "patriotic art" were sent to 2,500 people around the globe and select media outlets, promoting the noble intentions and work of the Empire. These bold, graphic-style cards, urging galactic citizens to accept and even join the Empire, reflect the political landscape of the upcoming animated series.
When Supreme Chancellor Palpatine first declared himself Emperor, many people in the former Republic welcomed the change after the chaos of Clone Wars. As this campaign shows, the Empire continues to build upon that goodwill with glorified images of the stability and security that were ushered in by its might. It's easy for worlds newly welcomed into the expanding Empire to be swept up with such ideas, though those citizens who have witnessed the ruthlessness of the Empire firsthand know the real story.
Thus far, the cards have appeared online at IGN.com, ETonline.com, Empire.com, Mashable.com, TheForce.net, and UOL.com. They were designed by Amy Beth Christenson, a member of the Lucasfilm Animation art department working on the series, and can be viewed in the accompanying slideshow. (But don't be too swayed by their message.)
Star Wars Rebels is scheduled to premiere in fall 2014 as a one-hour special telecast on Disney Channel and will be followed by a series on Disney XD channels around the world.
