The Sign in Sidney Brustein’s Window by Lorraine Hansberry is a powerful exploration of identity, idealism, and the messy intersections of personal and political life. Set in 1960s Greenwich Village, the play follows Sidney, a disillusioned intellectual and struggling writer, as he grapples with his marriage, friendships, and a world in turmoil. When he impulsively supports a local political campaign, his ideals are tested, and the cracks in his world deepen. Through sharp dialogue and emotional intensity, Hansberry challenges the audience to confront hypocrisy, racism, and the cost of apathy in a society on the brink of change.
