Ludwig Wilhelm, Glasmalerei, Rottweil a. N. 1890-1913: eine Gedenk- u. Empfehlungsschrift mit Bildern zum 25. jährigen Bestehen
A German commemorative and recommendation booklet from 1915, issued by the Rottweil stained-glass studio of Ludwig Wilhelm to mark twenty-five years of business, probably by its author Franz Xaver Singer, and aimed at prospective clients. Its plates show church windows in leaded and painted glass, including Gothic-style panels with heraldic shields, Jugendstil ribbon-and-wreath designs, and a sample window with a central figure, giving designers a range of period glazing patterns and armorial motifs.
