Hello "Alf"
It's very easy to call someone a "vandal" without checking the facts.I suggest you talk to a few artists  and than you'll fast discover that the vast majority of "art dealers" are in fact accountable to absolutely nobody conman and conwoman.There are thousands of examples to prove it and your silly insistence on describing them only in positive "professional" and gloving terms is dishonest,stupid and plainly detrimental to all concerned.Get your facts right before you talk.Plain and simple.
