As a teacher I was delighted with this theme of course.
This photo was taken in a folklore museum in Mittersill, Austria. It shows a class room from the early 1900’s. The class rooms in the Netherlands, where I live, were absolutely the same at that time, blackboard and all. I love the Writing!
We’ve come a long way in the last century. Today my “blackboard” in class is computerized and touch screen :)
