This Gadsden flag is set on a yellow background and features a black coiled timber rattlesnake, sitting on a patch of green grass, beneath which sit the words 'Don't Tread On Me' in black. The Gadsden flag was created by politician Christopher Gadsden in 1775 during the American Revolution.
The Gadsden flag is often used in the United States of America by libertarians as a symbol for such movements as limited government, gun rights and individual freedom.
