German textbook for learning French

"Französisch elementarbuch von Gustav Ploetz Ausgabe H" (Gustav Ploetz's textbook for learning French H Edition) is, as the name suggests, a German book for learning French. Originally published in 1909, my copy comes from 1913. It is signed W.Lehmann B1 (B1 is most likely a class designation, probably high school). The book itself is in perfect condition, which is truly amazing considering its age (110 years old). The back of the book also has shiny prints of contemporary French currency, photos from life in France, and a map of old France. I included only the most interesting pages (in my opinion) in the photos, and I will probably share the rest in the future in a mischievous video of me flipping through the pages.
