The suffrage map on a postcard from the successful 1917 campaign for an amendment to the New York State Constitution granting full suffrage to women. It includes a statement that suffrage had been adopted in seven new states since January 1917, and therefore "Electoral votes from Woman Suffrage States increased from 91 to 172." The card bears an ink stamp saying it was "Sent you by Mrs. F.J. Curley Captain, 2nd (Your) Election District" and was likely a get-out-the-vote reminder.
