I dunno.. It could be perfectly legitimate.
If you look carefully, the sunglasses are NOT wraparounds. They have FLAT fronts, and the sides have leather blockers to keep the sunlight from coming in the sides. Not unknown at the time.
The shirt looks to be period, with the wider collar that Tshirts of the time had, and a front that was likely stencilled. Probably a university logo. Given his apparent age, that’s very likely.
Sweater.. hard to tell.. but it doesn’t look like it zips up, and open-front sweaters are very uncommon in this day and age.
The camera? Can’t see enough of it. I’m guessing it’s a perfectly normal, period camera, just mostly hidden from view. Look at the guy in the front row. That’s not exactly huge.
I’m thinking ‘University student, probably a footballer (short hair, slightly unshaven), possibly direct from classes’.
Now, the guy *behind* him.. he’s from Neptune.
