I don’t remember what was used in printed materials. Probably Fraktur as you suggest. In high school we used Latin letters with arrows. At university in the 1990s, they gave us a photocopied sheet with handwritten Sütterlin and Greek letters in the first lecture. The professor wrote the lecture notes onto a blackboard and we copied them by hand. It was definitely Sütterlin. But I believe nowadays people use Latin letters.
