Rembrandt works called into question by experts in the Netherlands

Conservators at the Mauritshuis gallery in The Hague have called into question the attribution of three paintings long believed to be by Rembrandt van Rijn. Technical analysis revealed an underdrawing beneath *Portrait of Rembrandt with a Gorget* (c. 1629), proving it is a copy and that the original is in Nuremberg. *Tronie of an Old Man* (c. 1630) may be by a student or employee, and *Study of an Old Man* (c. 1655), though signed by Rembrandt, shows less accomplished brushwork and a date applied later in different paint, suggesting studio production. All three works remain on view in the exhibition *Rembrandt?* (17 April–13 July).
