Rather uncommon vintage black fountain pen signature on a 2x4-inch tan card, acquired in-person by an inveterate New York City-based autograph hound in the early 1950s. In good condition. 5'11", 170-pound boxer-turned-character actor Maxie "Slapsie" Rosenbloom played Runyonesque thugs and pugs in films like Nothing Sacred (1937), The Kid Comes Back (1938), The Amazing Dr. Clitterhouse (1938), Mr. Moto's Gamble (1938), Each Dawn I Die (1939), Irish Eyes Are Smiling (1944), and Abbott and Costello Meet the Keystone Cops (1955). After a run as Big Jule in Broadway's 1961 revival of "Guys and Dolls", his health rapidly deteriorated, partly owing to dementia pugilistica, the result of far too many blows to the head while boxing.
