The Empire wants you to join the fight and crush the rebel resistance. So naturally they are using propaganda to recruit new soldiers. These posters come from the beautiful Star Wars: Imperial Handbook Deluxe Edition, which is on sale now.
Here’s the official description:
The Empire has taken hold of the galaxy. Soon, with the completion of the Death Star, its control will be absolute. In preparation for this Imperial expansion, high-ranking officials from each branch of the Imperial military have set down tactical guidelines and procedures as well as collected mission reports and classified documents for all newly ascending commanders. In the wake of the Battle of Endor, members of the Rebel Alliance intercepted this top-secret instructional manual and have circulated it among their own commanders, who have added notes and commentary in the margins.
