Emma Sproson (left) and a friend chalking the pavement, 1907. Suffragettes who went on 'chalking parties' had to be careful, they were advised to go in twos or threes, never alone. Purple, white and green chalk was used. Sproson, who was from Wolverhampton, left the WSPU following the departure of Charlotte Despard, Edith How-Martyn and Teresa Billington-Greig to form the Women's Freedom League. She had twice been arrested, serving six weeks in Holloway Gaol and three months in Stafford Gaol, and had a reputation as a 'mob orator'.
