Can’t find either the title or the year of painting.
Skrepetsky (Семён Скрепецкий) was a Russian [I assume, amateur] artist who painted grotesque neo-primitivist caricatures of modern Russia, and built up a bit of a fame online. He has been shot and killed yesterday in Biała Podlaska, Poland, where he has lived since 2021.

More likely as in “has no formal education in art”
That would typically be called naïve art rather than amateur.
All artists are amateurs?
