Universal Ship Cancellation Society
http://www.uscs.org/
NOTE: Perhaps an unfortunate choice of names! The Society does not
actually cancel ships (I'm sure you're relieved), but promotes the study of the
history of naval vessels, naval postal markings, and other postal documents
involving the U.S. Navy.
