A Salty WWII German Nazi Banner

This salty NSDAP banner has an interesting story. I bought it from a guy who snagged it while fishing and fished it our of the Mississippi river. It was in a bag with a couple of heavy rocks. It is a multi piece banner with a separate white circle and separate black swastika stitched to the red background. I'm not sure how long it was in the river but it survived!
