I believe I have a poster of the full piece of art. If I'm right, it's entitled "Ghosts I Have Been" and is by an artist who goes by "Rowena." The piece was probably done as cover art for the young-adult novel of the same name, by Richard Peck. I'm a fan of the book and thought maybe you were as well. I do recommend it, though not if you have objections to ghosts and psychic powers in fiction.
