Punched mark, dated circa 1888 on the lid of the featured stein. Theodor Wieseler was obviously a Royalist. When he left Scheffler to start up his own company, Süddeutsche Glasmanufaktur - Theodor Wieseler, he took the same stein design, and same subject matter with him, but sold it with his own base mark.
Kaiser Wilhelm II, together with his wife, Kaiserin Augusta Viktoria and son, Kronprinz Wilhelm. Portrait is probably dated in the year of his accession, 1888.
