When you turn the image upside down you see someone with their arms upwardly outstretched. Hair is growing in the armpits which meaning the person could be male or female. We don't see a nose or any lips. We see someone with their eyes open looking upward which if they are hanging upside down means they are looking towards the ground, probably because they have gone beyond the point of watching the person who has put them in that position. The person has downward shaped eyebrows, they don't have a natural arch like many people do, so that eliminates quite a few people. I realize this was the 1970s when many women didn't shave their legs or armpits or shape their eyebrows, the natural look was in but it still doesn't alter the fact that there are several different eyebrow shapes that are normal growth patterns. We also see the neck of this person, where the skin is stretched from the area of the Adam's apple to what would be the tip of the chin. I believe the person has their mouth slightly open from exhaustion, they are beyond fear, judging by the distance from the area between the eyes and where the bottom of the chin is. There are two different kinds of anatomy when it comes to the neck. One is a clearly defined shape that follows the jawline from the bottom of the chin to where the jawbone meets the neck. The second one is a less clearly defined jawline where an extra pad of skin/fat hides the jawline. Both are genetic. The second group of people are usually those who end up with a turkey neck when laxity sets in, for want of a better descriptor.
