All Star Flags has a full line of Gadsden Flags for sale in several sizes. These are the popular "Don't Tread on Me" flag with the coiled snake.
The Gadsden flag is associated with Christopher Gadsden, who was a delegate to the Second Continental Congress. He presented a flag to the Provincial Congress of South Carolina on Friday, February 9, 1776. The journal of the South Carolina congress describes the flag as "an elegant standard, such as is said to be used by the commander-in-chief of the American navy; being a yellow field, with a lively representation of a rattlesnake in the middle, in the attitude of going to strike, and these words underneath, 'DONT TREAD ON ME!' "

The First Navy Jack flag has a red and white striped horizontal background with an outstretched (not coiled) snake and the Don't Tread on Me text.
