Quite special inscribed black fountain pen signature on a 4x6-inch tan album page to which the star added the name of the jazz standard he composed in 1931, "It's Sleepy Time Down South," acquired in-person in the 1930s by an autograph hound named Ethel. In good condition, with a crease to the upper left-hand corner and one fleck of soiling, away from the writing. 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.
