There is an idea that great art overcomes its propaganda over time, but the written word rarely does that. The visual and musical realm? Sure. But the nature of written propaganda tends to remain written propaganda, as though art can't arise from it. And when the art does arise from it, it tends to so heavily subvert the propaganda that barely functions as propaganda and gets banned within its lifetime.
You can read Platonov's ability to demonstrate misery via his characters speaking in a sort of Soviet Realism and realize why he wasn't that popular for it, and then read the earnest Soviet Realism and find no art in it. Meanwhile the Soviet visual art is often enjoyable long after its initial purpose.
So you can see good visual art in that Thor comic panel, but reading it is fucking painful for how god awful and dated it appears in its own era. That's probably the most defining characteristic of written propaganda, it reads as though its dated as soon as its published. It's stuck in temporarily and the average person won't like it. Art can't be stuck in time.
