Issued by Stempel in two weights in 1911. [Reichardt]
Digitally revived by Delbanco (2003, relatively light and loose, with some jagged contours), Petra Heidorn (Moorstation, 2004, tightly spaced, soft details, used for the sample), and Gerhard Helzel (2006). Only latter includes both weights. See also 19th Century Retro.
