Sigmund Freud's Marble Tablet

1963: Grinzing, Austria
Sigmund Freud was an Austrian neurologist who became known as the founding father of psychoanalysis. He wrote once to his friend, Wilhelm Fliess: "Do you suppose that some day a marble tablet will be placed on the house, inscribed with these words: 'In this house on July 24th, 1895, the secret of dreams was revealed to Dr. Sigm. Freud'? At the moment I see little prospect of it."

Today: Warehouse 13
The artifact was bagged by Artie and Joshua after a group of 7 teenagers dared each other to lick the tablet.
