Hoping this will come to me before someone replies - but here goes:
When I was a teen I found a stash of magazines or supplements in my parents' loft from the 1970s. They were a collection or set of magazines or supplements (possibly in those days you had to subscribe and they'd send you one every week until you had the full set).
I was fascinated by them because they were all about sex, relationships, society and similar topics - stuff my parents never talked about!
The publishers has a very distinctive name or was very well known at the time - two surnames I think? But I cannot for the life of me remember.
I remember spending hours in the loft reading them!
Does anyone have a clue?
