CAUTION "Don't Tread On Me" FLAG Wear Gadsden flag as a shirt! PACE HIGH SCHOOL Now you can wear the Gadsden flag as a shirt! Depicting a rattlesnake coiled and ready to strike, this classic symbol of American independence has stood strong for over 200 years. The symbol, which was originally used within the independence movement leading up to the American Revolution, is still just as powerful today as it was in the Eighteenth-Century. Yellow with Black/Green on front, reads "Don't Tread On Me"
