This photo was taken on November 16, 1968 when Robert A. Ferguson, author of several titles on health and telepathy, was giving a speech at a Spiritualist convention in Los Angeles, California. Faintly appearing next to Ferguson is a figure that he later identified as his brother, Walter, who died in 1944 during World War II. At first is seems possible that it could just have been an double exposure, but this photo being an Polaroid, the theory of an double exposure seems quite unlikely.
