@Walter Hinteler,
Actually, David, that kind of "Schnurrbart" (moustache) was quite common in the 1920's - in Germany and Austria, for instance.
Here's a painting from that period, by
Felix NussbaumFelix Nusbaum
And this one (like the above, pre-1925) by
Rudolf Schlichter
Both my grandfathers had similar moustaches - around 1918/1919, when they married.
