By the way I see that this is tagged as "anachronisms," and "period goofs," that's not quite
what I mean. Not the obvious goofs like a car in the background that wasn't actually made yet at the time the movie was supposed to be set.
These glasses weren't a mistake per se, they are supposed to look like they're from the 40's -- and they kind of do -- but they have enough of an 80's feel to them that you can ID that photo as being from the 80's, not the 40's. It's the kind of thing that slid at the time -- they looked "normal" in 1983 -- but now you go "whoa, what's with the glasses?!"
Anyway, that's my idea, but if this becomes more standard anachronisms that's fine too.
