Re: Veronica Zemanova
That SET is known as "392" and was released by "Sex Woche" magazine (1998, issues #29 & #41, and 1999 issue #25)
It has like 12 images in total, no penetration, of course.
Its date is pretty close to her B/G video, as well as SET 394 (released in 1997 by "Das Neue Wochenend" magazine on its issue #37)
So, the "Grial" should be somewhere around 1997-1998.
Also, would be better to remember Precioza Video / Rabbit, which made SETs of Veronika using dildoes (but videos were restricted to tease & masturbation only).
Other good thing to look at, could be next to AEN.TV network, which probably died keeping "hotter" stuff Veronika did after her boob surgery.
All of this if staff members are still having rights on that stuff and Veronika didn't buy any rights about them, otherwise, we're on Veronika's hands to see such things (not likely it'll happen).
However, you can see complete references about these and other B/G SETs at her fanmade website index.
