Highly uncommon vintage ballpen pen signature on a 4x5-inch pale green autograph album page, acquired in-person in the 1950s. In good condition, with a tiny nick to one corner tip. Somewhat of a poor man's Humphrey Bogart, good-looking Gerald Mohr was a regular in B noirs and detective flicks, playing a mixed bag of villains and gumshoes in Charlie Chan at Treasure Island (1939), Lady of Burlesque (1943), Gilda (1946), The Notorious Lone Wolf (1946), Passkey to Danger (1946), Dangerous Business (1946), The Truth About Murder (1946), Hunt the Man Down (1950), and Detective Story (1951). He also made a considerable number of contributions to the horror, sci-fi and fantasy genres, memorable in The Monster and the Girl (1941), The Adventures of Captain Marvel (1941), The Catman of Paris (1946), Invasion U.S.A. (1952), My World Dies Screaming (1958), and The Angry Red Planet (1959). He died tragically of a heart attack at the age of 54.
