Like in the Trunk interview of Rudolf Schenker, http://www.metal-rules.com/zine/content/view/791/ repeats the story on how the cover came to be, this time from Francis Buchholz. It also talks about the identity of the girl, and the designer and photographer are probably listed somewhere as well for connecting the dots, but I'm guessing that if she really wanted to be public about it, like Spencer Elden has been, her name and all would be known and we'd be quoting her interviews now. As it is, there aren't any and the people yelling abuse will just have to believe the sources closest to the original. Schenker repeats the history of the cover at http://www.bigmusicgeek.com/Scorpions_1.htm as well. Sources from before the Internet era would be nice though. Anyone have a good local library with music mag archives?
