Well, I've seen, like, old Soviet posters and such, but contemporary socialist propaganda, made here on Turtle Island or made by someone else and intended to wind up in the Anglosphere, no, can't say I've seen any. What little pro communist stuff I've seen, I'm not certain qualifies as "propaganda", it's often rather high level theory concepts and/or very self critical and nuanced and "all sides". Western takes on historical socialism are so bad that what I tend to consider "the best I can really expect" is the sort of stuff that at least acknowledges the role the Soviets played in defeating the Nazis and that the West was wrong to use them as a battering ram against Germany and then screw them over immediately afterwards. Like, at this point I'm happy for people here to say pretty much anything that at least acknowledges communists aren't ontologically evil and the USSR wasn't a foreign theocracy they were battling in a Crusade.
