Pastaud, in Limoges, France, sells on 14 May 2017 a "Flemish School, ca. 1630, follower of Frans Francken" "The Meeting of Melchidezek", estimated at 2,000 to 3,000 Euro.
As a copy after De Vos, the work should be dated closer to the end of the 17th century. The estimate probably stays about the same.
UPDATE: again for sale at same auction house on 28 January 2018 for an estimated 800 to 1,000 Euro, which is a bargain.
