A woman - likely Alice Paul, although the picture does not specify that - works on the suffrage flag of the National Woman's Party in 1919 or, more likely, 1920. Each star sewn on the flag represented a state that ratified the 19th Amendment to the United States Constitution, the amendment that gave American women the right to vote.
When the 36th star had been sewn on, representing Tennessee's ratification in August, 1920, Alice Paul unfurled the flag from the second-floor balcony of the National Woman's Party headquarters.
