Anniversary Day (play)

Anniversary Day, or Helen's Betrothal is a 1868 Australian stage play set in Sydney. It was "written by a gentleman of Sydney" (John Marwick).

According to the Sydney Morning Herald the play "appeared to give considerable satisfaction. The scene is laid in Sydney; the plot is carefully constructed, a moderate amount of the sensational being introduced to render it more attractive; and it was placed upon the stage with considerable care."

Empire praised the "genuine ingenuity" of the play. Another item in the same paper called the play "well written".
