I don't think you would find paintings like these on Primary School walls! They may look similar, but in reality are not. There is great skill involved in laying down oil paint like Van Gogh. Also.... Van Gogh had some very severe mental health problems, so who knows what was going on in his mind when he painted them, or how he actually saw his subject. He may have had a deep emotional feeling looking at his subject......and these paintings were his attempt at conveying that feeling, even if he didn't succeed very well, and we don't understand them. But they are very sought after, and the prices have just escalated beyond any sense or reason. As those of Rolf Harris could also do at some date in the future!
I find it fascinating to find out what people's favourite piece of Art is......would you, Saasher and CeeDee like to share yours?
