Since around 2013 handprinted copies of this print regularly show up (are fed into) the auctions (eBay). They are said to be “Nachlass” edition prints (numbered ../100) created by her “relative” Hans Brookmann (I have seen nrs; 7, 19 and 66, but is not impossible I missed more than one other copies). She is one of the pioneering women printmakers known to have been a student of Berlin Secessionist George Mosson and must have been known to Emil Orlik. 

As a printmaker this is the only example known. She is oterwise known as a painter 

Compare her print with the large nude by Else Schmiedeberg who also had been taught by Mosson and was acquainted with Emil Orlik through the VdBK school in Berlin.
