Actress Julie Stevens (1916 - 1984) was one of Gummo's clients. Stage work was excluded from this contract; the words "theatrical" and "vaudeville" were removed; that change was initialed by both Julie and Gummo. The contract was effective from 1939 to 1946. During that time frame she appeared in the movies Private Detective (1939), Honeymoon Deferred and Tear Gas Squad (both 1940), Castle on the Hudson and Murder in the Air (both uncredited, both 1940). No movies from 1942 to 1946. She also worked in radio (which was covered by this contract), although I don't know if she was on radio during her contract with Gummo. It would appear that Gummo started as President of Zeppo Marx, Inc. and was later demoted to Vice-President. His signature reads "Gum Marx". In 1939, an actress/agent contract could be simplified to one page.
