You Can't Miss: Back in the USSR

This week on the blog I follow, I uncovered a post about Lithuanian movie posters from the Soviet years. They have some oppositional propaganda influences, but I'm not sure exactly what the message is in all of these posters because I don't know enough of the background. Regardless of lack of historical knowledge, the images are still beautiful. Can anyone else tell what the embedded message is? If not, maybe you all can just admire the originality of design like I do.
