The following information is NOT printed on this postcard:
Witchcraft, in various historical, anthropological, religious and mythological contexts, is the use of certain kinds of supernatural or magical powers. The concept of witchcraft is normally treated as a cultural ideology.
The "witch-cult hypothesis", a controversial theory that European witchcraft was a suppressed pagan religion, was popular in the 19th and early 20th centuries. Since the mid-20th century, Witchcraft has become the self-designation of a branch of neopaganism, especially in the Wicca tradition following Gerald Gardner, who claimed a religious tradition of Witchcraft with pre-Christian roots.
The postcard is very popular for a variety of reasons.
