I love old photographs of mediums, they’re usually so beautiful. The pictures below are from The Perfect Medium: Photography and the Occult. This one is from 1921, the photographer was Staveley Bulford, and the medium was Miss Evans.
This is from 1925, and it’s of Mina Crandon, aka Margery. There are many posts here about Mina. If you put Margery in the search box on the upper right you’ll find them. The photographer is only credited as Gerke, and the pictures show ectoplasm coming out of Mina’s nose and ear.
