Aelbert Cuyp after Jacob Cuyp, is this son copying father?

A painting after the original Portrait of a Child by Jacob Cuyp (1594-1652) held in the collection of the Städel Museum in Frankfurt. This work has the same dimensions as the original, however the original is painted on a wooden panel as opposed to this version which is oil on canvas.

This painting is significant when considering the role Jacob Cuyp played in the artistic apprenticeships of some of the most significant Dutch Baroque artists of the time, namely his son Aelbert Cuyp (1620-1691). Aelbert became one of the leading Dutch Golden Age painters and arguably more revered than his father Jacob.

With the canvas fortunately remaining unlined, our conservator’s opinion is that the age of the canvas is near to that of the original. With further consideration of the fine quality of the finished painting, in our opinion, it is probable to be that of a close follower of the period, possibly Aelbert himself. Could this be son copying father?

According to Arnold Houbraken, Jacob Gerritszoon Cuyp assisted Jacques de Claeuw, Isaac van Hasselt, and Cornelis Tegelberg in establishing the Guild of Saint Luke in Dordrecht in 1642. According to the Netherlands Institute for Art History, he was a pupil of Abraham Bloemaert in Utrecht and became a member of the Dordrecht Guild of St. Luke on 18 July 1617. Cuyp became the later teacher of the painters Ferdinand Bol, Rafaël Govertsz Camphuysen, Aelbert Cuyp, Benjamin Gerritsz Cuyp, Hendrik Dethier, Isaac van Duynen, Bastiaan Govertsz van der Leeuw, Paulus Lesire, Aert van der Neer, Pieter Hermansz Verelst, and Ary Huybertsz Verveer.
