Richard Clarey who confessed to over 100 murders starting when he was 15 years old and living in Germany.  Clarey was sentenced to life without parole.

8 1/2" x 14" amazing artwork from one of the, if not the best prison artist, let alone with name recognition. He has written on the back, "The meaning of my existence is that life has expressed a question to me. Or, conversely, I myself and question which is addressed to the world, and I must communicate my answer, for otherwise I am dependent on the world's answer. Borrowed Strength."
This piece includes skulls, prison bars, swastika, a pentagram, spider webs and much more. Hand signed on the front, Clarey.
