mountains in palm of hand.... no applause, please.

Hello to all the Sloane fans, I'm the heir to a very important piece that I believe should be reproduced for the public too see, it's titled "A Map for Pilots showing Long Island, New York and all nearby Pastures for Flying Machines" it's signed "Socked into Metal for Ed Sonner by the Old Metal Socker, Eric Sloane" . It's dated 1937 twice....Ed was my Great Uncle, The weird thing is it's made by debossing or etching into "metal", aluminum I think and black ink, it measures 17"x 22" and has Ed's airman certificates and Quiet Birdman ID card pressed between the glass that protects it, obscuring 20% of the piece...Earhart,Hughes,Lindberg and all aviators of the day are mentioned, in extreme detail to the point a magnifying glass reveals more than the naked eye can see....It is a Treasure.... maybe a Treasure Map.... Gardiners Island is a known location of Pirates Booty.... and my family's heritage includes Morgans.... any suggestions on how to release this to the public.......since 9/11 it's taken on a strange meaning, it has to me anyway.
