Divination rituals such as the one depicted on this early 20th-century Halloween greeting card, where a woman stares into a mirror in a darkened room to catch a glimpse of the face of her future husband while a witch lurks in the shadows, may be one origin of the Bloody Mary legend.

This Halloween greeting card from 1904 satirizes divination: the young woman hoping to see her future husband sees the reflection of a nearby portrait instead.
