1970s film with "Hypno Queen" in the title?

[Schoonergonda]

I've always wondered about this one. Growing up, I remember seeing a nearby city's newspaper, on the movie pages, somewhere around 1975 or so. I saw a small ad in the corner of the page from one of the cheap grindhouse-type theatres and the title read "Carla / Hypno Queen". I was amazed. I wasn't sure if this was two movies or a longer title of one ("Carla the Hypno Queen", maybe?) and I have never been able to find out.

Ring any bells for anyone? As I mentioned over in the "When Did You Realize That You Were Not Alone" topic on the media board, this was the first hint I ever had that there was an audience for explicitly hypno-themed stuff. . .
