"Dutch Painter, 16th c." seems to be by Vincent Sellaer

Cambi, Italy, sells on 4 May 2016 a "Dutch painter, 16th c." "Female figure with putti", estimated at 6,000 to 8,000 Euro.

It is a better version of a work by Vincent Sellaer (Flemish, not Dutch) sold 10 years ago at Artcurial for nearly 6,000 Euro, and so should be worth more than the estimate (image from artvalue.com). However, the Sellaer market seems to have gone a bit flat lately, with multiple works not selling or selling rather cheap, so perhaps the estimate, despite not recognising the artist, is spot-on anyway. The work for sale is larger than the one sold ten years ago, so if these dimensions are correct, it isn't the same work. Otherwise it has been restored, which was obviously much needed.

UPDATE: not sold, in an auction were the Italian paintings fetched high prices but the others struggled mostly.
