Judith Leyster self-portrait at Christie's
December 6 2016

Picture: Christie's
There's a wonderful self-portrait by Judith Leyster at Christie's in London, which I hadn't really paid much attention to until I came face to face with it on Sunday. I also hadn't realised that it's a new discovery (Christie's press office, where were you?) which has only been known to art historians through a reference to the painting through the inventory of Leyster's husband, Jan Miense Molenaer. The picture is quite different from Leyster's earlier and more famous self-portrait, which is in the National Gallery of Art in Washington. The estimate is a very enticing £400,000-£600,000. It's from a UK collection - and I hope this picture can be acquired by a UK museum.
Update - some last minute digging in the attic of the vendor has uncovered the below family catalogue from 1957.
Interestingly, the picture was then known as a Leyster, but half a century later the identification had been lost, providing an interesting puzzle for Christie's specialists.
This happens quite a lot - indeed I've seen pictures appear at auction as 'sleepers' which had been sold as the real thing only a decade earlier. It's amazing how much information can be lost when one generation passes on. The analogy I often use is this; how many of us know the names of our great grandparents? Not many, I suspect, without looking it up. And yet we know so much about about our grandparents.
The moral of the story is - always put a label your paintings!
