New Mondria still appears regularly, often working in private ownership. Since the publication of his index in 1998, in which 1,400 works are described, about 30 new works have been added.
Most often these are portraits, but there is also free work, especially from the period when Mondrian was still painting figuratively. Wietse Coppes expects to add another work soon, but this is still under investigation.

Pioneering abstract art

Mondrian painted many portraits, for friends, but also for a commission, for a total of 93 portraits. It was a way to make money. From 1915 his work began to become more and more abstract. Therefore he is seen as a pioneer in abstract and non-figurative art.

His later geometric works, with distinctive horizontal and vertical black lines and primary colours, are particularly world famous. He was one of the most important artists of the De Stijl art movement. His most famous work is Victory Boogie Woogie, painted between 1942 and 1944, while he was living in New York. This work is pending in the Kunstmuseum The Hague.

All the images that have now been discovered are privately owned and therefore cannot be seen by the public. The painting by Betsy Bergman-Cavallini is also privately owned, but it temporarily hangs in the Jan Konin Museum in Os.
