Reminds me of another Dutch forger called Geert Jan Jansen who was active until the mid nineties: https://en.wikipedia.org/wiki/Geert_Jan_Jansen https://en.wikipedia.org/wiki/Geert_Jan_Jansen He imitated a wide variety of painters and even got one of them (Karel Appel) to authenticate a forgery as real. He later opened a gallery where he now sells paintings signed under his own name in the style of several famous painters with very different styles. He's made quite a nice career doing that since he got caught. When he was still forging, he sold lots of paintings and drawings via auction houses all over Europe and it is suspected that there were quite a few that were never found out or where the owner decided to not press charges for financial reasons. So, there are likely to still be some of his forgeries in private collections.
