15 " Dive Flag with Hogfish. If you like Scuba Diving or know somehow who does, this sign will make a great addition to any Nautical Themed room. This sign is made out of marine grade Aluminum, so the sign will never rust. Making it out of Aluminum also makes it light in weight, so it is easy to hang. We paint our signs with Candy automotive paint and automotive clear. Using automotive paints and clear ensures this sign will look good for a very long time. We make all our signs here in house at our shop in Florida.
