| $400.00 | Gold--Joyce | Chart-of-the-Supposed-Course-of-the-Florida-Stream | Graphically arresting thematic chart of the "Florida Stream" or Gulf Stream with its flow northwards up the east coast of the United States, well past Bermuda, and then into the North Atlantic Ocean. Direction of the Gulf Stream current is shown visually by arrows supplemented with written notations indicating the compass direction at several locations across the stream.

The map may be considered to be an example of persuasive cartography. The concept of the Gulf Stream was novel at that time (hence the "supposed"); many mariners had not fully adopted the notion when this map was published. The direction and flow of the Gulf Stream was proposed by Benjamin Franklin in 1770 based on measurements he took during voyages from the U.S. to England and France.
