Hello~ Uncle Sam!

Uncle Sam is the national personification of the United States and sometimes more specifically of the American government, with the first usage of the term dating from the War of 1812 and the first illustration dating from 1852. He is depicted as a serious elderly white man with white hair and a goatee beard, and dressed in clothing that recalls the design elements of flag of the United States—for example, typically a top hat with red and white stripes and white stars on a blue band, and red and white striped trousers.

The American icon Uncle Sam was in fact based on a real man, albeit a beardless one.A businessman from Troy, New York, Samuel Wilson, provided the army with beef and pork in barrels during the War of 1812. The barrels were prominently labeled "U.S." for the United States, but it was jokingly said that the letters stood for "Uncle Sam." Soon, Uncle Sam was used as shorthand for the federal government.

But Sam Wilson looked nothing like the Uncle Sam pictured above. Uncle Sam's traditional appearance, with a white goatee and star-spangled suit, is an invention of artists and political cartoonists. One of these political cartoonists was named Thomas Nast. Nast produced many of the earliest cartoons of Uncle Sam. 

The most famous image of the Uncle Sam persona was a World War I recruiting image that depicted a stern Sam pointing his finger at the viewer and declaring, "I want you". It was painted by artist James Montgomery Flagg in 1916, just prior to US involvement in World War I.
