I like to switch out my PC's wallpaper pretty regularly usually in accordance with whatever has been interesting me recently. I would love some wallpapers with vaguely communist/socialist/leftist influence but searching for this doesn't bring up much that looks better than something a graphic design student would make their freshman year of college. Especially at the 3440x1440 which is the resolution I am aiming for.
I'm specifically looking for pretty art or propaganda (silly or serious). Y'all got any?
I used this poster by Lissitzky for a while: Beat the Whites with the Red Wedge.

Also, this website has a large collection of soviet art, but it's not great resolution. I've been able to find higher resolution copies of some things just by googling it.

When I'm bored sometimes I'll go through online collections from museums and such. You can find a lot of stuff to download in high res
