Anonymous Flemish "Head of Christ"

Rob Michiels, from Bruges in Belgium, sells on 26 November 2016 a "Flemish School, 16th/17th century" Head of Christ, a 53 by 45 cm oil on copper estimated at 400 to 600 Euro.

While the work looks familiar, I can't immediately find another version of this composition. The style reminds me vaguely of the works of Pieter Claeissens II, and in any case seems firmly set in the tradition of Bruges.

It seems to be some slightly more modern mixture of two Memling works, Christ Blessing and Christ Crowned with Thorns, with a similar nose and eyes, simple clothing (not the richness one can see with Massys and so on). But it clearly isn't a Memling or anything of that level, and looks to me more like a 1520-1540 painting.

The face of Christ without further attributes (like the crown of thorns) is a rather unusual subject: it may be that this is a fragment of a larger work, perhaps a Salvator Mundi. Another possibility, which would explain why he is looking to the side instead of at the viewer, is that it was coupled with a second panel, presumably a depiction of Mary.

As a strong, well-painted and original image, it should be worth 2,000 Euro.

UPDATE: sold for 800 Euro, double the estimate but clearly less than I expected.
