The front of the seal is identical to the coat of arms, without the horses and motto banner.
The back portrays liberty vs. tyranny with a woman that represents liberty; her left hand holds a wand topped by a liberty cap (a French symbol of liberty), her right hand holds a drawn sword. She is trampling upon Tyranny, represented by a lion. The entire design is encircled by the legend "Both Can't Survive."
