My parents are super anticommunist but basically historically illiterate. As long as it’s not super obviously communist, a photo of the hammer and sickle, Stalin, Marx, Che, or Fidel they probably won’t recognize it. That said, any of you comrades have some good, ideally high quality, phone wallpapers? All the ones I’ve found online are kinda mid lol.
The first thing that comes to my mind is a beautiful wheat field. Wheat wreaths are often featured in communist iconography.
With the hammer and sickle imagine often associated with communism, the sickle is used to harvest the wheat, and represents the agrarian part of the community that produces the food for everyone.
