The copper "bone key" found with the skeleton of Chester Copperpot. This prop replica, as well as my treasure map, were recently part of a year-long exhibit at the Mariner's Museum of Newport News, Virginia as part of the "Swashbuckler: The Romance of the Pirate" exhibit.
It will soon be part of another year-long pirate-related exhibit at the Whaling Museum in Cold Spring Harbor, New York.Here is the bone and map as displayed at the museum.
