Nifty 7.25 x 9-inch borderless black and white portrait as Dr. Zachary Smith on T.V.'s science-fiction favorite "Lost in Space," boldly signed in black felt-tip marker in-person at a film convention appearance about two decades ago. In good condition, with two thumbing impressions at the bottom, invisible when the photo is viewed head-on. Snarky character actor Jonathan Harris was unforgettable as the show's dastardly, effete stowaway who toiled endlessly to botch the Robinsons' various efforts to return to Earth. He made several other contributions to the horror, sci-fi and fantasy genres, chiefly on television, including two classic episodes of "The Twilight Zone," entitled "Twenty-Two" (1961) and "The Silence" (1961).
