TOUGH to acquire 8x10-inch black and white portrait of the likeable television and film actor as stuttering Bill in the terrifying T.V. adaptation of Stephen King's It (1987), boldly signed in black felt-tip marker at a film convention appearance about 15 years ago. In good condition, with a sticker from the third-party authentication service J.S.A. affixed to the lower left-hand corner and accompanied by its matching certificate.
