Hey, that's the same one I was taught in the Netherlands in the late 80s! It seems to have been replaced with an English-style in recent decades though, is that the case in Germany as well?
It's fascinating how similar-yet-subtly-different the cursive writing is across Europe. I wonder if you could map them into something similar to language families (or type traditions, I suppose). Would there be any "language gradient" equivalents for cursive writing across the continent? Well, before the industrial revolution I guess, I'd expect that after that you'd see more singular influences of designers backed by the state pushing for standardization of education.
According to the wiki, the Schulausgangsschrift is mandatory in 5 states and optional in 4 states (out of 16) (probably on a school/teacher level). So it still seems to be taught in some places.
After searching a bit more I discovered the situation is similar in the Netherlands too: schools can choose between the two styles (or more like three publishers each with their own styles, really).
