Torrente ads from L'Officiel 622, 1976.
I have to admit the location from these ads reminds me of the orgy scene in The Stud (which is severely overdo for a post of its own), especially the swimming pool in the second spread. Since that cavernous pool room has always been one of my favourites ever, I could quite happily move right into these ads- clothes included.
