One for Stig and Clint; an LVG C.VI in 1919 with Deutsche Luft Reederei (DLR) operating an airmail-passenger service, and still with wing crosses and lozenge camo. The company logo and white numbers were on the LVGs. The furry man in the rear cockpit is famous film actor Hans Albers; with a Jewish wife his popularity must have seen them through the 30s and 40s.
