Thing about Monet, van Dyke, and all the others... They literally were the bansky of their day.
The establishment did not like their work. It was porn, abstract, weird, not proper art! Yep that and more was slung at them, and their work didn't sell that well. No one wanted to pay much if they did sell them.
I mean, who wants a wonky drawing of some sunflowers in a badly drawn case? Oh, now you do, cos it's worth millions. 100/200 years ago, you'd have been alone in wanting it.
It was only 20 years ago someone paid a million for half a cow, or millions for an unmade bed!
Or that idiot that bought a strip light.
So today, the main big thing is STREET ART, not graffiti (scrawling initials etc on a wall or even over art, or a street sign). Now the "fogies" don't get IT! whatever IT is‽
Bansky does some amazing art, and some do even better (locally we have lots of street artists) even if some is very political.
I went to the bansky exhibition, and it was really interesting and some quite thought provoking, some I agree was a bit rubbish.
His take on constable's haywain, was really good and made you realise what we're doing to the countryside.
To just rubbish his art, cos YOU don't get it, is fine, but admit you don't get it, and not say it's crap.
I did a HND in Photography, and at the end of each assignment, we put.our work on the wall, no one was allowed to say... That's crap, or brilliant, without saying WHY.
I continue that method today on art, TV, film, whatever I give an opinion on.
