Flemish School "Rest on the Flight"

Loeckx, Belgian auction house, sells on 24 November 2015 as lot 337 a "Flemish School, 16th century" Rest on the Flight to Egypt, estimated at 15,000 to 20,000 Euro.

The same composition, but in a horizontal version, is listed at RKD as "Anonymous Antwerp Manierist or manner of the Master of the Antwerp Adoration". I actually prefer the one for sale, but that may be due to condition issues.

The composition and style go back to older Flemish models, more specifically by Gerard David and Joachim Patinier (apart from the central figures, one can compare e.g. the basket in the RKD version and in the pictured Patinier version (bottom)).

I haven't found a closer example and can't pinpoint a possible painter for the version for sale, but it is a very nice 16th century Flemish (Bruges?) painting, and should be worth its estimate.
