A 1907 Boston exposé of spiritualism by Hereward Carrington, drawn from the Harry Houdini Collection at the Library of Congress, written to show readers how fraudulent mediums faked physical phenomena. Its photographs are plain, close-cropped studio views of hands and a man's face, with dark suits and pale cuffs against grey backdrops. A designer might borrow their stark, documentary tone and the way hands alone carry a gesture of concealment or trickery.
