What a neat, historic picture!
Sadly, the wall and the history of it are being misused by the ultra left wing radical extremists in reference to a certain other wall being constructed in this country. I still have a map that I got as a teenager back in ‘62 of Berlin and the depiction of the wall and fencing in use at the time. It shows the city divided and has lots of statistics on it. A lot of folks have NO clue.
