The era of Fame!
I expect @GoodProspect to comment here just so I can see their Keith Haring avatar in an 80s-appropriate topic.
And if you want to see some 80's art
some really kool pics in that first post
The pics seem to be more late '70s than any point in the '80s. I'm going by the hairstyles and movie marquees. Could be up to '81. 1982 at the most.
