You are so right Mike.
It's one of those things that makes art so fascinating.
There is a body of opinion that considers accurate realism to be the most accomplished but let's be honest, it takes incredible observation, amazingly controlled motor skills and a very good eye for colour etc., but the creation of the picture is limited to choosing the best angle or composition.
When photography came along artists were forced to re-think so added things to a scene or removed them or found a way of looking at all sides at once (cubism) but then photography developed to a point where this could be done by trick photography or developing techniques, SO, artist found ways of playing with colour effects or suggesting something without showing anything etc.
As things change, artists find ways of using new materials or colours or light etc.
This is why the first cubist paintings like this one are important and therefore expensive
where a later, and better painted image might be dismissed as inferior.
As you said Mike, the ARTISTIC THOUGHT and application is what counts.
We all know of modern art that seems to be rubbish to us both it wins a prize. Somebody sees or understands something important?
Returning to the subject, it appears that often, when a major theft takes place the paintings stolen are not always THE MOST EXPENSIVE. As far as the thief is concerned he tends to go for something seen in a catalogue or book and recogniseable and worth LOTS of money.
As long as he can move it on for a profit he doesn't care.
Thanks for encouraging me to write this.
