Secretaries' conference, she appeared with a silk poppy pinned to her coat and distributed twenty-five more poppies to attendees. She then campaigned to have the poppy adopted as a national symbol of remembrance. At its conference in 1920, the National American Legion adopted the poppy as their official symbol of remembrance. Frenchwoman Madame Guérin was invited to address American Legion delegates at their 1920 Cleveland Convention about 'Inter-Allied Poppy Day.' After the convention, the American Legion too adopted the poppy as its memorial flower and committed to support Madame Guérin in her planned U.S. Poppy Day. It was also following this event that the American Legion christened Madame Guérin as "The Poppy Lady from France." Madame Guérin successfully organized the U.S.'s first nationwide Poppy Day during the week before Memorial Day in May 1921 using silk poppies made by the widows and children of the devastated regions of France. When the American Legion stopped using the poppy symbol in favor of the daisy, Veterans of Foreign Wars' members supported Madame Guérin instead. Using French-made poppies purchased through her, the V.F.W. organized the first veterans' Poppy Day Drive in the US, for the 1922 Memorial Day. In 1924, the Veterans of Foreign Wars patented the Buddy Poppy (original name). Madame Guérin's 'Inter-Allied Poppy Day' idea was also adopted by military veterans' groups in parts of the British Empire. After the 1921 Memorial Day in the US, Madame Guérin traveled to Canada. After she addressed the Great War Veteran Association on 4 July, the group also adopted the poppy emblem as well as 'Inter-Allied Poppy Day' concept. They were the first veterans of the British Empire (predecessor of the Commonwealth of Nations) to do so. Madame Guérin sent Colonel Moffat (ex-American Red Cross) to Australia and New Zealand (and probably South Africa) afterwards as her representative. She then traveled to Great Britain, where she informed Field Marshal Douglas Haig and the Royal British Legion about her idea. Because it was an underfunded organization, Madame Guérin paid for the British remembrance poppies herself and the British Legion reimbursed her after the first British Remembrance Day Poppy Day on 11 November 1921. By 1921, remembrance poppies had become widely accepted through the Allies of World War I as a flower of remembrance to be worn on Armistice Day.
