After three different experiences buying through Invaluable, I can confirm and assure that all three pieces of art are fakes. They sell pieces under the name of the original artist and shield themselves in their terms and conditions, but the truth is that after more than five months writing to the support service, I haven't received any answer.

The three auction houses are still repeatedly selling fakes and are doing nothing to stop it. Invaluable is protecting all these auction houses from fraudulent auctions. And this doesn't mean that all the auction houses that use Invaluable are fraudulent, but a VERY high percentage are. Just do a Google search to find hundreds of results on different pages and videos.

It's a shame, this seriously damages the credibility of the industry. Shame!
Stay away from Invaluable if you're looking to buy an original piece.

When they took NO responsibility, did not return calls, talked big but ZERO follow-up.

No. Not until my win was shipped to me.
