Is named for Queen Elizabeth I, and was the home of Thomas Jefferson. Perhaps something to do with those figures, such as a picture of the Declaration of Independence, would be good?
Michigan, the land of a thousand lakes, could also be represented by something to do with recreational fishing. Like a fishing pole, some fishing flies, or a picture of a salmon. You can also go to the grocery store and buy some Land O'Lakes butter, from Michigan.
Cheers,
