For me, some of the most interesting exhibits at the Museum of Witchcraft concerned a few of the British witches and occultists who reinvigorated and reinvented the Old Religion in modern times. For example, the Museum displays a silver chalice that belonged to Aleister Crowley, ceremonial magician and occultist, creator of the Thoth tarot deck, who was popularly known as "The Great Beast." Another display has a few artifacts that belonged to Stewart Farrar, the creator of Alexandrian Wicca.
A large glass case contains a painting of Gerald Gardner, the creator of Gardnerian Wicca, along with various of his possessions . . .
. . . including his High Priest ceremonial robes.
These are the kinds of things that make the Museum of Witchcraft unique!
