An Alabama group is working to get an official state license plate featuring the Gadsden flag, the yellow Revolutionary War-era flag with a rattlesnake and the words “Don’t Tread On Me” that has become popular with Tea Party groups.

The Foundation for Moral Law, a Montgomery-based religious liberty group that has taken on cases dealing with abortion, marriage, and public prayer,  is working to get 1,000 pre-orders, the threshold that must be reached before the Alabama Revenue Department will manufacture plates, according to the Associated Press. Arizona, Missouri, Oklahoma, South Carolina, Texas and Virginia now offer license plates featuring the flag.

The plates cost $50, with $41.25 of that going to the Foundation for Moral Law and the remainder going to the state. According to the group, the funds raised from the plates will “used for defending the Constitution of the state of Alabama and the U.S. Constitution.”

The Alabama Department of Revenue currently offers 43 specialty license plates on its Web site, including one for cattlemen,

saltwater fishing,

Sons of Confederate Veterans,

and the National Wild Turkey Federation.
