The painting depicts an artist painting a woman dressed in blue posing as a model in his studio. The subject is standing by a window and a large map of the Low Countries hangs on the wall behind. It is signed to the right of the girl "I [Oannes] Ver. Meer", but not dated. Most experts assume it was executed sometime between 1665/1668, but some suggest the work could have been created as late as 1670–1675 — wikipedia
The painting has only two figures, the painter and his subject, a woman with downcast eyes. The painter was thought to be a self-portrait of the artist; Jean-Louis Vaudoyer suggested the young woman could be his daughter. The painter sits in front of the painting on the easel, where you can see the sketch of the crown. He is dressed in an elegant black garment with cuts on the sleeves and on the back that offers a glimpse of the shirt underneath. He has short puffy breeches and orange stockings, an expensive and fashionable garment that is also found in other works of the time, as in a well-known self-portrait by Rubens — wikipedia
