Alexander Deineka (Alexandr Deineka) was a very politically engaged painter/illustrator. He was born in 1899 in Kharkov (Russia). His best work (in my opinion) is his least political (revolutionary) work. Most of all I like his folky, simple drawings (with the slightest touch of goache, or water color). Unfortunately I couldn't find many examples on this website which is
devoted to his work.
In his later paintings there are traces of the work of Alex Katz, Edward Hopper (Deineka being the influencer obviously, if at all). He keeps combining (social) realism and slavic nostalgia
