A (nearly) new publication by the German Mining Museum in Bochum I just discovered is concerned with the work and the assets of the famous German industrial architects Fritz Schupp (1896-1974) and Martin Kremmer (1895-1945).
On more than 400 pages it lists all their industrial buildings and shows what is still there.
Hundreds of high resolution images and plans complement this catalogue.
The Bergbaumuseum shop offers it as a real bargain right now. Unfortunatly only in German.
