Still unidentified printmaker. He is not mentioned in any of the artists lexicons or in Dressler’s “Kunsthandbuch” ed. 1930. All further information (prints, identification, biography) is very welcomed. 

This nice print “Adagio” must be his Opus Magnum. Far more famous, loved, and appreciated artists have created similar scenes….. Eva Roemer, Helene Mass, Arie Zonneveld (above, clockwise) and there are many more examples.
