This article is actually very interesting:
While most of the other magazine stories are entirely fictional, this one seems to be a an actual portrait of Gina Janssen, and since it's in German, which many or most people in this forum might not understand, I'll write a little bit about.
The article even mentions her birthday as in April 1953, which perfectly fits with the article in
this post, which says she's 29 (and that article first appeared in autumn 1982).
The quoted article says she's 26 and that her latest movie was "Drei Schwedinnen auf der Reeperbahn", which is from 1980, so the article should have appeared in early 1980.
It also says she was born in the German Democratic Republic (GDR) - in German it's Deutsche Demokratische Republik (DDR) - and moved to Hamburg (West Germany) with her family in 1967, at the age of 14. Later she worked as a dental assistant for 4 years - that must have been from 1969 until 1973, because the article says she changed to photo modelling in 1973.
The other article I linked to pretty much mentions the same facts: it says she's from Hamburg, worked as a dental assistant and started modelling at around 19 years old (which would be something between 1972 and early 1973).
But one thing in the quoted article made me laugh: her reply to the question, how it feels like to act naked in front of the camera. I translate it for all non-german-speakers - Gina replied:
That's funny, how can she (as well as the author) claim she didn't do porn so far? It was 1980 and she'd done a lot of porn by that time, including mainstream movies like "Agent 69 Jensen i Skorpionens Tegn" (1977). Did she do all her porn work completely uncredited at that time?
However, while this porn thing of course is a lie, all the rest sounds authentic to me, also because the article basically tells the same facts that are also mentioned in the other one, which appeared in a different magazine about 2-3 years later (actually about one year before she disappeared for good!).
