My grandmother in 1916 third from the right just before being arrested by Wilson for protesting the War. With some of the "ladies". I did like the hats.
As per Google it is Women's Day and in New York they meet on the Brooklyn Bridge. Somewhat fitting, my great grand father was one of the first across it at its opening, his son, my grand father married Hattie Kruger above. Interesting set of confluences. So watch for my grand daughters!
