the entire book? There's a short pictorial history of each army assignment the Division had. It appears it was published @ mid 1920s by the typeface etc. It is entitled: "Die 26. Infantrie Division (1. Kgl. Wurtt.) im Krieg 1914-1918 Zussammengestellt im Divisionsstab", by Stable & Friedel in Stuttgart. It's paperback and no author is listed although there's almost no text-it's almost 100% photos from peoples' collections (seemingly every Offcr Stllvtr. had a camera by the credits). I can post some more of the photos here if you'd like from the summer, 1916 section. Feel free to use them as needed as copyright has long since evaporated from the original photographers.
