Today you make me work...
I say that today an expert reads everything, also our conversations on on Findartinfo, because today information pass through the books, the museums, but also through the media, also e-bay, the television, the auctions online. Then the expert makes him his opinion.
If someone desires to have one authentic signed, pay an expert that writes and puts is signature.
The authentic one doesn´t perhaps have any value, for a house of auctions. I don´t know it.
But I tell you that if you buy an object from a sale and then this object is a forgery, the house of auction doesn´t respond any authenticity.
The house of auctions puts in condition the buyer to personally see the object put in sale.
If you buy a Caravaggio, declared as Caravaggio on the catalog, but then the Caravaggio is false, you are not indemnified. Worse for you, that you have not looked at it well, when the house of auctions has shown it, before the sale.
This is my opinion. I hope to have been clear.
