from the Grosse Pointe News 1971
Since I set up a Gundella timeline -- which is far from complete, let alone barely started -- I might as well post some of the smaller adverts from one of her early Witchcraft courses. These are from 1971 at the Grosse Pointe Memorial Center. The six week, twelve hour course cost $35 and each successful "Witches Apprentices" received a diploma. Although the snippet mentions that the class was meant to be "tongue in cheek" I'm not so sure that she or her students thought of it in that manner.
Case in point is this very interesting story about one of her former students, who despite being from a very prominent and wealthy family which owned an entire island at one point, still had her signed certificate from Gundella on the wall even though she was approaching 90 years of age (at the time the article was written in 2002; she is still alive and may still have it up as she approaches 100!).
