The bolshevism propaganda section has 1 polish anti bolshevik poster and 1 german one. I dont think the bolsheviks were really of a mind to portray themselves as the giant skeleton monster enveloping the world. Maybe trotsky would think of that, but i dont think that one would be published. It also only covers russian civil war era posters, posters from stalin onward may as well have come from the brain of Josef Göbbels because the subject matter was nearly identical (though obviously it excluded Christianity entirely, being depicted neither positively nor negatively beginning with stalin's regime). The one poster of the astronaut saying "there's no God here" is from the khruschev era, who was a militant atheist who persecuted the church more severely than stalin. But this was a one-off throwback to earlier propaganda that was more than likely thought up by khruschev himself, most of the propaganda about the space race was also superhumanistic, realist, and positive in nature following the precedent set by stalin.
Part of this is because stalin and hitler were both admirers of realism and traditional art forms. But the subject matter depicted in soviet posters did indeed change dramatically all its own, it wasn't just the art style that changed. Not saying that the soviet union turned good, or anything of the sort, just saying that posters are unreliable and if we looked at soviet propaganda posters from the same era as Germany, instead of earlier bolshevik ones, we'd have a hair up our ass to start believing that the USSR was a paradise on earth too because the propaganda after Lenin died was almost always positive rather than negative.
If you want to see really pretty outlandish and bizarre looking posters, you can also look at italian and falangist (before franco) propaganda posters. Extremely modernist and futurist in design. They were somewhat similar to early bolshevik posters in design but obviously they were different in what they depicted. And they took the futurist art style to its logical extreme and oftentimes the posters were just disjointed shapes with a message attached to it.
