Vintage inscribed black fountain pen signature on a 4x6-inch tan autograph album page, acquired in-person in New York City in 1941. In good condition. A former news reporter with a dark mug and streetwise attitude, Horace MacMahon proved the ideal urban thug, henchman, impassive bouncer, or smart-mouthed cabby in crime flicks of the 1930s and 1940s, including The Last Gangster (1937), The Gracie Allen Murder Case (1939), Another Thin Man (1939), and Lady Scarface (1941). Following his success in the uncharacteristic goodhearted role of Lieutenant Monaghan in the 1949 Broadway play "Detective Story," he found new work on the other side of the law, playing hard-nosed cops and unrelenting gumshoes, most memorably Lieutenant Mike Parker on TV's "The Naked City" (1958). His credits in other genres included roles as Danny Thomas' agent on "Make Room for Daddy" (1953), Mugsy in the sci-fi-themed comedy Abbott and Costello Go to Mars (1953), a bartender in a classic episode of "The Twilight Zone" entitled "Mr. Bevis" (1960), and one of the Penguin's henchmen on "Batman" (1967).
