A really fast US History lesson

I've been on a bit of a nostalgia kick with watching old Smothers Brothers Comedy Hour. (No, I'm not old enough to remember when they first aired but I did see the revival version when they were first run and the old ones in rerun when I was a youngster) In a few of the episodes they showed these really neat films.  One about the history of the US and another just covering 1968.  I thought I'd share them with you here. 

To any new readers who came via my Her Universe fangirl of the day profile, welcome!  I hope you stick around.
