Don't Tread On Me
The Gadsden flag. Considered one of the first flags of the United States, the flag was later replaced by the current Stars and Stripes (or Old Glory) flag. Since the Revolution, the flag has seen times of reintroduction as a symbol of American patriotism, a symbol of disagreement with government, or a symbol of support for civil liberties. You can order this on any color shirt but traditionally it's on yellow (Daisy).
