Bold signature in blue fountain pen on a beige album page, 4.4 x 6.  Fine condition, with a mild diagonal handling bend at the left of the page, not affecting the writing; and a stray light ink mark near the bottom right, well away from the writing.  Clifford Odets is best remembered for his politically engaged Depression-era plays, including Waiting for Lefty, Awake and Sing, and Golden Boy.  His Hollywood screenplays included The General Died at Dawn (1936), Humoresque (1946), and, most notably, Sweet Smell of Success (1957).  A notation on the reverse side indicates that this autograph was obtained in person in November 1941.
