Literature

Illus. in Joppien, Elisabeth Treskow - Goldschmiedekunst des 20. Jahrhunderts, Museum für Angewandte Kunst Köln 1990, p. 154, no. 209: "Die Brosche Emil Lettrés stammt aus der Zeit um 1910-15 und zeigt getriebene Blätter und Äpfel. Sie entstand für die Mutter der jetzigen Besitzerin. Wegen ihres kleinen Ausmaßes entschloss man sich Anfang der Sechzigerjahre, die Brosche mit einem größeren Rahmen zu versehen"; see also colour plate p. 72.
