To whoever it may concern Sadly I have to publish it in this way but there isn't another option to reach decision makers at Catawiki (which is an online auction house). I have been purchasing at Catawiki for a while now and I have to say most of it was a pleasant experience till recently. I was buying mostly antiques. Few months ago I wanted to try my luck with contemporary art.  I have bought several pieces here and there and then I realized that artists I was intending to collect have started to disappear. I have tried to contact so called "experts" obviously without any good results. Then I realized that there are always the same names listed there. Tatiana Ruiz was one of most used expert names and some guy Anthony I believe. They keep selling (really hard) exactly the same artists with the same copies of their work  (dozens of them at each auction) without giving a small space for new talents and variety. They have privatized Catawiki and when you see what they sell there it looks fishy. You can't even contact them.    I don't know who really runs the show at Catawiki but please consider changing your art repertoire or simply change your "art experts".Thanks for understanding
