This ceecee movie Black Porno Session. The image off the cover was used in adverts in British mags in the mid to late 70s in a low quality version, but amazingly uncensored
as shown in the sample page from a Lovebirds mag (credit to Memory hunter
http://vintage-erotica-forum.com/showpost.php?p=2133844&postcount=61) to tantalise us hardcore-starved Britons. The colour pic of the box was found by me on another site which displays images of vintage porn stuff, but gives no information about digital versions or where they might be found. Links to ceecee films are tabu here, but a personal message is ok
. It would be great to see this movie after nearly 40 years, the film was released in 1973.
