A common academy bookend with a pencil-and-erasable back.

These common academy bookends sometimes evoke even more vivid memories.
Actually, aside from Newton's notation, I have nothing to comment on.
This is just a video of a very common bookend handed out at academies back then.
I can confirm this: I received this bookend at least before 1992.
