It is a very fine portrait, much better than most of these "School of" works, and I wonder if it isn't by the master of the Bruges Portrait school of the time, Pieter Pourbus the Elder.
Pieter Pourbus (1523-1584) is the first of the Pourbus family to become famous; descendants include Frans Pourbus the Elder and the Younger, and Pieter the Younger. He was Dutch but worked almost whole his life in Bruges. The paintings which are attributed to him are of varying quality, but some of the better ones are closely related to the composition we have here.
Benson, portrait of Anne Stafford
Pourbus, Portrait of a Lady, Metropolitan Museum
The only other painter from the period and region who in my opinion was capable of such good portraits was Ambrosius Benson, but the work for sale more closely resembles Pourbus in my opinion.
But whoever painted it, 7,000 Euro seems cheap to me and it should be worth closer to 20,000 Euro, also considering its relatively large size of 95 by 68 cm (large for the type of painting that is).
