For historians of British mens' magazines, Sue's Mayfair set is from Vol 6 Number 11 - which is November 1971. The discreet display of pubic hair is typical of the date.
On the other hand, at that time bare breasts were still allowed on cover pages. I seem to remember the date bare boobs were banned from display on covers as the summer of 1985. I might be a year or two out however.
