I believe these pics are publicity stills from the off-Broadway play, "The Dirtiest Show in Town" (circa 1968). Celebrity Sleuth states that Adrienne appeared in the play "Stag Movie" in 1971. I believe their info is incorrect because she was working in mainstream Broadway by this time.
"Stag Movie" may have been an alternate title for the play I saw or another play entirely. Adrienne's IMDb listing makes no mention of her early career in New York while Wikipedia has a brief synopsis for that period.
I saw the play in the dingy little hole-in-the-wall theater in the Village in 1970. By then Adrienne was long gone, replaced by an "actress" who would have been OK but she was about six or seven months pregnant at the time and therefore did not appear nude (thank goodness). Fortunately the other nude actress was quite a looker.
The play was actually enjoyable; I wish I could have seen Adrienne, but she was a virtual unknown at the time so I did not know what I had missed.
There are other pics of her from around this time, some of which are stills from the play. Unfortunately, none I have seen show full frontal nudity which was a big no-no at the time.
