The image on his Christmas card is from a poster advertising the first march for women's suffrage in Washington, D.C. Organised by the suffragist Alice Paul for the National American Woman Suffrage Association, it saw thousands of suffragists marching down Pennsylvania Avenue in Washington, D.C. on Monday, March 3, 1913. The event was scheduled on the day before President Woodrow Wilson's inauguration to "march in a spirit of protest against the present political organisation of society, from which women are excluded," as the official program stated. Paul had gone to England to pursue further study, heard Christabel Pankhurst speak and joined the Women's Social and Political Union, being jailed a number of times. She returned to the States in 1910 and continued to campaign for women's rights. Women eventually gained the vote in the US in 1920 under the 19th Amendment.
