Another related work which has been said to be Jan Brueghel copying after Rottenhammer is a pictures sold in Cologne, Lempertz, November 25, 2000, #1120 (copper, 33 x 48.5); this one is illustrated in Borggrefe 2008, p.125, fig. 176. At least one actual collaboration between Jan and Rottenhammer must exist, probably the Munich/Augsburg picture, if Jan & studio were also producing further variants.
The present picture is, according to Werche, an authentic Van Balen from some time after 1620. According to her, Ertz had communicated to her that the collaborator was Jan the Younger although it is now included in the Jan the Elder book.
There is a copy of this in Antwerp, KMSK, also very large (100 x 218) and on canvas.
