Keith Hunter Jesperson serial killer known as "The Happy Face Killer."
8 1/2" x 11" four "Walled Street Bulletin" from the Oregon State Penitentiary Salem, Oregon dated February 12, 2009.
Hand signed on the back with a happy face drawn with his signature, Keith Hunter Jesperson. 
A rare example of his moniker incorporated into his autograph. Something which Jesperson claims the prison no longer allows.
