I collect "original" posters but auctions are full of fakes and modern day reprints. Does no one at Catawiki ever stop to think how there could be so many of the same poster? The same posters keep reappearing such as 1972 Olympics, Lambretta, Rene Gruau, Perrier Amsterdam Zoo and Grapus. But there are loads more. The meaning of original varies between Catawiki, its so called experts and its sellers. For example: "Original" - I just printed it or its a copy of the ORIGINAL or its the Original artwork copied, or I bought the artwork from an on-demand printer and its original. Rene Gruau is a favourite and even the artists Trust does not care. The so called experts can't be and they certainly can not have any integrity. They can't judge values because they never see the item. But they do have every incentive to value highly because the site fees are a percentage. Worst of all, if you are sent a fake Catawiki's customer service is terrible and YOU have to pay to send it back. Why the brand owners do not protect their intellectual property is odd. But then, when they do who will they litigate?
