The theme of oil painting is the small advertisement on the wall. Do you know who painted this painting?
If it's an oil painting, it must be super realistic, killing people, which is rare in China. You search for surrealist painters to see.
It's hard to say unless it's on the shelves. I remember Liu Guangyuan searching for pictures and mixing all kinds of newspaper advertisements. Wang Nanming made calligraphy paper balls, and I can't remember the rest.
