Quentin, from Berlin, Germany, sells on 22 April 2017 a "Flemish genre painting, ca. 1600" of a merry company, estimated at 3,500 to 5,000 Euro.
Sotheby's London in 2013, which was then attributed to the Master of the Female Half Lengths. It sold for £86,500.
While the original artist is thus clearly unidentified, the work for sale is a copy of lesser quality, but with some interesting variations which may help people define the original artist (if these variations are based on some original version of course). The exact allegorical meaning isn't really clear to me, but women, alcohol and music all seem to be foolish things to get involved with. Perhaps it is simply another Parable of the Prodigal Son. The estimate may be somewhat high for a clearly less skilled artist, but it is an interesting old work anyway and should be worth a few thousand Euros anyway.
