An art glass book with a history of its own

Gustav E. Pazaurek wrote (among other things) two important books about art glass in the early 20th century. One was Moderne Gläser (Modern Glass), ca. 1902, which was a contemporary account of glass being made in the jugendstil era, and the other was this book- Kunstgläser der Gegenwart (Art Glass of the Present), a contemporary account of art glass production in the early Art Deco period, written in 1925. I had the first book in my library already; in fact, Moderne Gläser is now in the public domain, and is available on Google books as an e-book! I recently ordered the latter of the two books from a seller in Germany. It was interesting to see the personal stamp on the inside of the book of a Mr. Pius Macho of Josephinenhütte in Schreiberhau. According to the book Josephine Glassworks 1900-1950 - Art Nouveau- Art Deco- Modern, by Stefania Zelasko, Pius Macho was an engraver at the Josephine Glassworks between 1920 and 1950. It's a nice coincidence to have a book that covers a particular company (among others) that was owned by an artisan working there when the book was written!
