Frieda Thiersch bound a number of the presentation certificates for the Iron Cross. There's an example at Yale (red morocco), and another in a private collection known to me. The binding is, as one might expect, supremely proficient although also (with its predatory eagle in gilt) unpleasing to the eye, especially to one who knows how fine Thiersch's work could be. The calligraphy (not by Thiersch, who did no work in this medium so far as I am aware, but possibly Anna Simons, d. 1951, who worked for the Bremer Presse also), is excellent...except for the nasty little squiggle at the bottom that was Hitler's signature. She, Ignatz Weimeler and a handful of others in Germany were doing bindings in the twenties and early thirties that were on a par with the best of what the London binders were doing. Paris? The 1920s and 1930s were so abundant with bookbinding geniuses like Legrain that I'm not sure I can stretch quite that far!
