Mr Castagna, you wont remember me, we spoke a couple of times last year on the phone, from Barcelona (Spain).A year ago I acquired a work by Willem de Kooning from a gallery in Vienna, without a certificate of authenticity or anything that could justify that it was an authentic painting.I was looking at how to confirm if the painting could be authentic or fake. I spent a long time trying to check it, I contacted various experts, auction houses, and I did not get anything. In the end I got in touch with you, and you gave me your personal opinion. That helped me to request a return of the painting, which in the end turned out to be false.Although we do not know each other personally, and probably we will never meet, I would like to thank you for your gesture, the detail you had with me and wish you well. He had this detail with a person who lives on the other side of the world.I want to send you a big hug from Barcelona, Spain, and thank you for this gesture you made with a stranger.
