"Jan de Beer" at Hampel

Hampel, from Germany, sells on 5 December 2019 a "Jan de Beer" Saint Christopher, estimated at 60,000 to 80,000 Euro.

The attribution to Jan de Beer is based on similarities they see with a De Beer (attributed) from the Prague Museum (the Narodni Galerie), but these seem rather superficial.

A much more closely related work is in the collection of the Detroit Institute of Arts, and is not attributed to an artist. The work for sale seems to be a slightly less well executed variation by the same artist or workshop.

The work offered now was sold by Christie's in 2012 as an "Antwerp School, ca. 1530-1540" work, and then fetched 145,000 Euro. Which means that, if sold at estimate, it would be at less than half price this time around... It's a good and interesting work, but I don't think it is by De Beer.
