The young lady’s pose pretty much sums up my perception of girls when I was a boy: effortlessly precocious, defiant, untouchable. Feminism seemed to be something they demanded by virtue of being alive, by candidly commanding a room or a conversation or the task at hand. It was an emanation, not a hollow phrase parroted about on Twitter.
The “shesmidas” on the cup is a watermark referring to the eBay store where I found the shot.
See another great found photo of the period here.

Same girl as in the “Love in a Van” picture.
They certainly look similar. Would be a trip if it was the same girl.
