From what i can make out with my limited German, the VDAV started in 1908 until 1936 and post war
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
The immediate post-war years saw some provisional activites, mostly on a local/regional level and even the re-establishment of a VDAV Gau Nordmark in the British-occupied zone. In 1950, the VDAV was properly re-formed as a nationwide association.
1991 saw another name change, now to DVF [Deutscher Verband für Fotografie]. The DVF is still very much active.
German-speaking members can find a 1908 - 1998 chronicle of the VDAV/RDAF/DVF on their website:

(It's the "Die Chronik des DVF 1908-1998" link. You will find the triangular VDAV/eagle design as seen on the plaque on pages 16 and 92 of that .pdf-file.)
