Well, I did live in the 60s and 70s; but you have to remember 'the past is a different country, they do things differently there'. A woman smoking was looked down on a bit, so few women smoked - it just wasn't considered appropriate. Maybe that's why the ads appear to target women - they were a market the cigarette companies were trying to break.
The three brands in the ds you linked to are Kool, Pall Mall, and John Player Special. I've never heard of Kool, I suspect they were not sold in the UK. Pall Mall - not sure I ever saw them in the shops either, although the brand seems familiar to me. JPS was a very well known brand - I rather think that ad may be trying to appeal to women, but also to kid men on that if they smoke JPS, that is the sort of woman who comes with them. (Yes, ads really were that blunt back then.)
