According to Florida Gun Supply's website, "This painting was painted in honor of Andy Hallinan for being a true patriot and leading the country into a better, safer America." The prints cost $50 each if you're paying by credit card and $48.90 if you're paying with cash. Buyers also are entered into a raffle to win Zimmerman's original painting.

Hallinan, the owner of Florida Gun Supply, made national headlines in July when he posted a video to YouTube declaring his store "a Muslim-free zone," saying, "I will not arm and train those who wish to do harm to my fellow patriots."

Now,  Hallinan is being sued.

"The first flag I painted on this canvas was an American flag, but (I) decided to repaint over it with the Confederate flag when I heard Andy was getting sued by (the Council on American-Islamic Relations)," Zimmerman said. "The second flag I painted was the battle flag, which we need in America in order to protect the first."

According to the website, Zimmerman and Hallinan will split the proceeds, which will go toward "their legal funds, living expenses and advancing their mission to change the country."

According to Zimmerman, his last painting sold on eBay for more than $100,000.
