At the Smithsonian Museum of American History, there was plenty of things that showed the various symbols of America. Uncle Sam here is the more modern personification of America.
So is Lady Liberty though she's more on the "liberty" part than just the United States government. This Statue of Liberty has a color that would have been more similar to the original color if it hadn't become green by mistake.
I could be mistaken but I think this Statue of Liberty was made to protest the plight and bad treatment of Hispanics in America.
I also saw this old war poster, the woman is supposed to be Columbia who was the personification of America before Uncle Sam. Most depictions of Lady Columbia aren't exactly "beautiful", but this Columbia is gorgeous. That's a lady worth fighting for!
