The prototype of the Rohrbach Ro VIII Roland airliner, presumably photographed soon after its first flight. The airframe was delivered to Lufthansa with the name Zugspitze, but soon moved on to Spain to become M-CAAC, one of the first aircraft of Iberia. Returned to Germany in August 1928 and rebuilt as Ro VIIIMb bomber. Photo from: SLUB / Deutsche Fotothek
