Is it 1958 or 1976?

Look, girls, this was a class in 1958 on Picture Day!  Maybe your grandparents were in classes that looked a little like this one!

This was a class in 1976!  

....and here you are in 2017!

Maybe someday your children will look at this picture!  I wonder what they will think!
