Babuino, from Italy, sells on 22 January 2018 a "Jan de Bray" family portrait, a large canvas (154 by 215 cm) estimated at 10,000 to 15,000 Euro.
It is a good work, but some aspects of it make me doubt the De Bray attribution (given by Didier Bodart in 1992: from what I can see, he is a knowledgeable specialist, so take my comments based on online images with a grain of salt please).
The work was offered at Babuino already in July 2017, then with an estimate of 40,000 to 60,000 Euro, so this second offering has an immense discount already.
This doesn't mean that the work for sale is a bad painting, far from it, and it is close to Jan De Bray in the sense that it is also probably Dutch and from the same period. Now, this is the richest period in Dutch painting history, and the number of good portrait painters active then is just staggering. So finding the actual artist responsible for this painting isn't easy.
All in all, it should for now be considered an anonymous Dutch work by a good painter, but not by an absolute master, and probably thus not by De Bray. The current estimate is probably about right, even though it was probably intended as a come)and-get-me low estimate for a real De Bray.
I'll try to find an artist who actually is really close to this style, but for now this is the best I could find.
