Vanderkindere, from Brussels, sells on 13 September 2016 a"Probably Dutch school (?) 17th century" Denial of Saint Peter, estimated at 1,000 to 1,500 Euro.
It is the (over-)cleaned version of a painting sold at Rops (also in Belgium) in May, which was then estimated at 2,000 to 3,000 Euro and sold for 2,000 Euro, against my advice that "I certainly don't believe it is worth as much". In that blog post, I had identified it as a "reversed copy after one of the masterpieces of Gerard Seghers, "The Denial of Saint Peter"". They now have the right subject but omit the origin of the image. I'm not convinced it's a 17th century copy either.
The current estimation may be right (or still too high), but after paying 2,000 Euro plus auction costs plus the costs of cleaning the painting, it must hurt to only get back a probable 1,000 Euro minus the auction costs.
UPDATE: sold for 1,400 Euro, seems still too high to me.
