"Britain's Day" throughout the United States was marked by demonstrations in New York and Washington. Both cities were smothered in flags, while fetes, dinners, and outdoor concerts were held, as in many cities. Contingents of Canadian soldiers were invited to participate in the celebrations at many border towns, and addresses eulogizing Britain's effort, both on land and sea, were delivered in scores of centers. Britannia is an ancient term for Roman Britain and also a female personification of the island. Uncle Sam (initials U.S.) is a common national personification of the American government. It was the James Montgomery Flagg image more than any other that set the appearance of Uncle Sam as the elderly man with white hair and a goatee wearing a white top hat with white stars on a blue band, and red and white striped trousers.
