Etching by unknown pupil of Rembrandt.
The print reproduces the painting signed: Rembrandt f 1634 in the Thyssen collection, Lugano (Bredius 370), in reverse.
Münz attributed the etching to Ferdinand Bol. It is, however, signed at the bottom right: I. de Jouderville (?); this is clearly visible in the Amsterdam impression, which is dated on the back in ink: 1648. (White and Boon)
