An 1874 spirit photograph by Édouard Isidore Buguet. The photograph features Amelie Boudet and the spirit of her husband, Allan Kardec, holding a sign. Kardec was the founder of “Revue Spirite”, a Journal of Psychological Studies.
Part of the sign reads:
“Amis, continues propager notre doctrine, adieu pour toujours”
“Friends, continue to spread our doctrine, goodbye forever”
