József Klein - Asphalt Pavers - 1928 - 1932 seems political to me. Communist or Union or Labor.
Lol, this really made me smile. Trust me, I know what you're saying as in the communist era, most of what the called art looked like this painting, but back when this painting was made, there was no communism. Communists came after. And yes, propaganda was pushed to the max.
That mural, from artistic point of view, looks amazing. I don't want to associate it with communism 😁 even if it reminds me of those ugly times. Thanks for the link Steve, it's highly appreciated.
