This is probably one of the most provocative pictures that model Pam Suthern, whom I last featured in August 2015, has ever been in.
And of course, it's from an ad for perfume. ;-)
Specifically, Charles of the Ritz perfume. The ad it came from first ran in the early seventies - 1972 or so.
Charles of the Ritz is gone, but fortunately we have this lovely photo of Pam Suthern as its spokesmodel.
