1812, PROBABLY DRESDEN, SIGNED S. MOHN F. 1812 AND A. V. P.

Until the departure of his son Gottlob to Vienna in 1811, Samuel Mohn was the sole signatory of his workshop's glass in Dresden. Following the loss of such an important decorator, Samuel promoted several of his junior painters to senior positions where they were entitled to include their signatures or initials alongside that of the master. August Viertel was one of these artists, the elder brother of Wilhelm Viertel, another painter employed by Mohn, August was to become one of the leading members of the workshop in Dresden. The last Viertel/Mohn countersignature can be found on a glass dated 1814, just a year before Samuel's death, see Paul von Lichtenberg, Mohn & Kothgasser, Transparent-Enamelled Biedermeier Glass, Munich, 2009, p. 131.
