Your description does not strike a bell with me, and I am not familiar with the piece that you describe. In answer to your question, purple, green and white in England were only the official colors of Emmeline Pankhurst’s Women’s Social and Political Union. Numerous other organizations also had their own official colors, the most prominent being the red, green, and white of the National Union of Suffrage Societies. Offhand, I do not recall any major organization using red and black, and I suspect that these were simply added on by the owner as decorative enhancement. Whether this tambourine was an actual suffrage piece or put together later, I could not tell you. Is the wording “Votes for Women” printed or hand done?
Crystal Eastman, another Vassar graduate like Lucy Burns , spent most of her life fighting for women’s rights, long after they attained the right to vote. She also participated in labor activism (writing a study called “ Work Accidents and the Law ” that helped in the creation of workers’ compensation laws) and chaired the New York branch of the Woman’s Peace Party. Eastman organized a feminist Congress in 1919 to demand equal employment and birth control, and following the ratification of the 19th Amendment, Eastman wrote an essay titled “Now We Can Begin.” It outlined the need to organize the world so women would have “ a chance to exercise their infinitely varied gifts in infinitely varied ways, instead of being destined by the accident of their sex.” The essay still resonates today in its call for gender equality in the home, financial support for motherhood, female economic independence and voluntary motherhood.
Stone then tried to gain practical speaking experience. Although women students could debate each other in their literary society, it was considered inappropriate for them to participate in oral exercises with men; women members of the collegiate rhetoric class were expected to learn by observing their male classmates. So Stone and first-year student Antoinette Brown , who also wanted to develop skill in public speaking, organized an off-campus women’s debating club. After gaining a measure of competence, they sought and received permission to debate each other before Stone’s rhetoric class. The debate attracted a large student audience as well as attention from the Faculty Board, which thereupon formally banned women’s oral exercises in coeducational classes.  Shortly thereafter, Stone accepted a challenge from a former editor of a county newspaper to a public debate on women’s rights, and she soundly defeated him.  She then submitted a petition to the Faculty Board, signed by most members of her graduating class, asking that women chosen to write graduation essays be permitted to read them themselves, as men so honored did, instead of having them read by faculty members. When the Faculty Board refused and Stone was elected to write an essay, she declined, saying she could not support a principle that denied women “the privilege of being co-laborers with men in any sphere to which their ability makes them adequate.”
