I've received the two-volume illustrate history of Red Vienna, The Wonder of Red Vienna (Das Wunder des Roten Wien) by Harald A. Jahn, which were kindly signed by the author. I had the chance to join Harald for coffee in Café Museum, just off the Ringstrasse near the Vienna Opera House ... and I look forward to another chat with Harald upon my next visit, perhaps at Café Sperl.
Harald's book is a remarkable body of research about the Interwar period of Vienna (1918-1939) known as "Red Vienna." The two-volume set features extensive color photos of buildings erected during that post World War I era. 1918-1939 was also a very prolific time for the Josephu brothers and some of their work is featured in Jahn's book.
In Volume 1, page 47, Josef's work is featured (pictured above) in a reference to the Albrecht Durer-Bundes, an artists association in which Josef was very active. In Volume 11, page 87, Josef's Zuflucht, located at Trostsrasse 68-70, Pernerstorfer-hof, is featured along with a photo we gladly supplied; with additional Zuflucht photos on page 110 and 111.
In Volume 1, page 178, Florian's Putto am Zierbrunnen (above) at the Sandleitenhof Library is featured. This work of Florian is also featured in Architektur des Roten Wien by Walter Zednicek on page 147.
