Vintage black fountain pen signature on a 3x5-inch off-white card, dating to the late 1930s. In good condition and ideal for matting with a favorite photograph. African-American vaudevillian-turned-Hollywood character actor Clarence Muse was typically cast in stereotypical roles, such as busboys, porters, chauffeurs, and the like, but was allowed to tackle more substantive material as racial barriers fell in the 1960s onward. He made several notable contributions to the horror genre, appearing in the Bela Lugosi classic White Zombie (1932), Black Moon (1934), Invisible Ghost (1941), and The Soul of a Monster (1944). He also had a small role, as a porter, in Sherlock Holmes in Washington (1943), which starred Basil Rathbone and Nigel Bruce as Holmes and Watson, respectively.
