These cards were produced by F. A. Lattmann in Goslar c. 1900. The maker's name is on all Deuces, and the logo on all Unders.
The Deuces and court cards are those of the standard double-figured Prussian pattern, the pip cards show views from the Harz mountains, where Goslar is situated. Lattmann has produced similar packs before and after that time, but with other views from those mountains.
The tax stamp on the Deuce of Hearts has the number 19 (for Goslar).
