I cannot find the name of the cover model of Playboy Germany December 1996 issue, titeled "Erotische Engel".
There is no data in the issue about the model or the photographer.
As far as I know besides the soft version which has been published, there was a more explicit version on the internet.
Some websites say that this is Annika Walter, a german diver. However it's a wrong information. The diver indeed was in the issue, but not on the cover.
