Guarantee of authenticity

Anyone who buys an object in Lehner art auctions, receives a guarantee of authenticity. The authenticity guarantee lasts 3 years from the date of purchase. Find more details in our GTC .

If the work turns out to be a fake, the buyer gets his money back and the consignor its object. Unlike all known auctions worldwide we will also be active when our knowledge changes over the authorship of a work and offer a discrete reversal. In order to determine the authenticity of our works, we use respective experts or heirs and executors. It is your right as a customer to buy authentic art.
