In haunting photos, the medium is the message

Nearly a third of American adults believe in ghosts, a recent Gallup poll tells us.

And if you're in that apparition-affirming group, "The Perfect Medium: Photography and the Occult" might be just the show for you.

The exhibit, which could have been called "I See Photos of Dead People," opens at the Metropolitan Museum of Art on Sept. 27 and runs through the end of the year. It includes approximately 120 photos, artifacts from the heyday of Spiritualism, roughly from the Civil War to World War II.
