Dark Force has released SECRETS OF SWEET SIXTEEN, promising a transfer from the camera negative.

I saw this film two or three times with different co-features at various drive-in theaters in the mid 1970's. It's one of those German "educational" (read: sexploitation) films about schoolgirls and their wild times. Way down in the cast is Christina Lindberg, who graced many foreign adult films. Not having seen it since the early 1990's, I look forward to revisiting it.
