The first thing that caught my eye is how thin everyone in that film stock looked.
People looked like that up until the late 70's, maybe the early '80s. Now, if you
see anyone in that age group who looks like that, that person will look way out
of place to the point of appearing abnormal.
At the time I graduated high school in 1981, just about every male student wore
a belt on his trousers, and tucked in his shirt. I never see that anymore because
it would only accentuate the gut bulging out and the rolls of flab hanging over the
the belt. People just don't look like that anymore. Then again, Type II diabetes
was almost not even heard of back then.
