Tubingen: Verlag Ernst Wasmuth, 1955. Hardcover. XII, 439p., profulely illustrated with expert sketches both descriptive and explanatory, plus artist's reconstructions (how such & such gate may have looked, &c). Hardbound in openweave blue cloth boards gilt and enclosed in the dust jacket. Nice condition: the book itself has a short bump to tail-rim, the only detraction from crisp squareness, top edge mildly dust-soiled, gilt remains bright, within find a neat small ownership signature. The dj wasn't so lucky; although complete it is very edgeworn with puncturing scratches. All in all a very good copy. Text exclusively in the German language.
