Elusive vintage inscribed black felt-tip pen signature on a 4x6-inch cream-colored autograph album page, acquired in-person in the 1970s. In good condition. Stone-faced character actor Eric Porter, who excelled at playing merciless, well-spoken villains, is best remembered as Professor Moriarty, opposite Jeremy Brett as the titular gumshoe, in Grenada Television's superb Sherlock Holmes series of the 1980s and 1990s. He was also noteworthy as Captain Larsen in Hammer Studio's The Lost Continent (1968).
