You're absolutely right, Max. I had forgotten that she did her hardcore under Colleen Brennan, as well as an interview in one of those "golden days of porn" programs.
I did manage to find a newsgroup pic of her in her "cover girl" days... That's her on the right. I don't know the young lady on the left, but the parts I can see look interesting.
And I apologize for the churlish tone of my comment about Roberta Pedon. The photographic chemistry of the day did make her hair look reddish in some of her pics, but no one meeting her in person would have taken her for a redhead.
