"Northern School" is close to Frans Floris

Herry & Muon, Beaune, in France, sells on 11 November 2018 a "Northern School, late 16th or early 17th century" Triumph of David, estimated at 1,500 to 2,000 Euro.

It is an oil on panel with a nice size (73 by 103) which was sold nearly ten years ago, in 2009, at Ketterer in Munich, according to the RKD. The painting seems to have suffered somewhat in the past 10 years though.

The style of the figures and faces reminds me of the work of Frans Floris, and a very similar work was offered at Dr. Fischer as "School of Frans Floris" with an estimate of 25,000 to 30,000 Euro! The work for sale is less enticing, but should still be worth around 4,000 Euro.

UPDATE: as was pointed out to me on Twitter, the RKD version is NOT the same as the one for sale now, but another (nearly identical) version in much better condition.
