Didn't see a thread for this photo. More for completeness than because I see anything useful, here goes.
I can't tell if the cloth in the background is the same blue one that shows in some other pictures. (In particular, maybe the Short-Haired Brunette Against Blue Background.) Perhaps the color comes from the lighting.
Besides the backdrop and a shelf behind her, there's a once-commonplace black rotary-dial phone. Those were getting old-fashioned by the end of the 70's, as I recall. I think the time is early-mid decade for that reason only.
Can't decide if she looks drugged, but she sure looks unhappy. I worry for her. On the other hand, she seems uninjured. There's not much to go on. She's not in any other of the released photos that I can see.
