I can't comment on most of these. However, as a Mississippi native, I do have to comment on the "Mississippi Plate". The steamers are known from the river that shares a name with the state. The steamers are not as much a part of the history or culture of the state itself. The current (or maybe old) license plate references The Blues, I'm glad to see that. But a better secondary would be the Magnolia Flower (which adorned Mississippi's license plates for decades). People all across the USA tend to confuse the State of Mississippi with the river; we don't need that on our license plates.
