Upside Down American Flag in Black. The upside down U.S. flag is an official signal for distress. I have the designs in red, blue, black and white. I also have this design on a variety of products that range from t-shirts, shirts, mugs, hats, bags, etc. They make great gifts for anyone for any occasion. What makes these products great, is that you're able to customize them to fit your wants and needs.
