Gadsden Flag (Don't Tread on Me) (USA Snake Flag) Poster

This design features the Gadsden Flag, a historical American flag that contains an illustration of a timber rattlesnake raising itself from the grass in an aggressive posture; there is a bright yellow background that covers the flag. The text says "Don't tread on me" in capital lettering. It is named after American general and politician Christopher Gadsden, who was active in the 18th century. He designed the flag in 1776, during the American Revolution, and it was adopted for use by the Continental Marines, which was the main naval infantry force of the American Colonies, later becoming the United States of America. It is often flown in modern times as a patriotic symbol, showing respect for American history and the struggle to achieve independence from the British Empire. It is sometimes also flown by supporters of libertarian political movements, since its message can be seen to express the importance of individual freedom against oppressive governments.
