This is exactly the sort of photo that would be used to advertise the sets of pics for sale in men's magazines back in the 50s and 60s. Just enough leg and cleavage to pique the interest of horny adolescents. I never ordered them when I was a teen but I did fantasize about doing so. This was what amounted to porn in those days. Yes, we have come a long way indeed.
