Surviving the Hindenburg: Charred Post Card

This charred postcard survived the Hindenburg disaster. Now part of a collection at the National Postal Museum, it was donated by John P.V. Heinmuller. The postal museum calls it a "philatelic gem," and provides this background information:

Postal officials salvaged approximately 358 pieces from the 17,609 estimated pieces of mail on the flight. Of these, 176 salvaged items were unburned (with a few exceptions) because they were stored in a protective, sealed pouch awaiting postal service on the return flight, and they later received a paquebot postmark.
