Ultra-rare vintage blue ballpoint pen signature on a 4x6-inch tan autograph album page, acquired in-person in the 1950s. In good condition, with an also scarce ink signature of legendary Disney voice actress Verna Felton on the verso. In good condition. The great Margaret Dumont was unforgettable as the haughty, straight-faced comic foil in seven Marx Brothers films, dubbed "The Fifth Marx Brother" by Groucho. She played similar roles alongside other great comedians, including W.C. Fields, Laurel and Hardy, and Jack Benny, by her own admission understanding virtually none of the jokes, which may explain why she was so uproariously funny. Not long after she signed this autograph, Dumont starred in her only horror flick, playing Persephone Updike in William Castle's Zotz! (1962).
