Yes, that’s why I said “generally”. But the value people place upon painting rocks also seems to be quite relative. When it was done by somebody thousands of years ago, then it instantly becomes a “priceless artefact” to be preserved and revered. I am not making any statements about what the value of this painting was, only that I do not trust others to make this evaluation on my behalf - especially when the rationale behind it seems so inconsistent.
