Several related drawings, including one in Amsterdam, Rijksprentenkabinet (inv. #1919:34), a drawing which Winner dates just before 1600 and he sees some connections with motifs from Coninxloo.
Lots of doubts noted in files at RKD on this one and I agree. There's some wierd streaking of surface that isn't like Jan, and figures don't have his usual verge.
When this was sold at Christie's in 1976 the catalog listed it as being on copper: which is it?
Copy Goteborg, Konstmuseet; parts of background borrowed by a follower in Forest Landscape in Leipzig, Museum der Bildenden Kunste; copy of same size but on panel (note this trend!) sold London (Christie's 5.ii.88 #132). The last of these is now accepted as Ertz 2008-10, #233.
