warum soll der Beleg nicht sammelwürdig sein? Wenn Du ihn nicht möchtest-ich wüsste einen Abnehmer....

.
Allerdings wäre mir der abgebildete Beleg auf der Rückseite (Missile Mail USS)"Barbero" in Original lieber..
- solche Belege werden mit mittleren 3-stelligen €-Beträgen gehandelt!
Zum Hintergrund dieses Raketenfluges:
Missile Mail In 1959
Barbero assisted the United States Postal Service
(USPS) in its search for faster, more efficient forms of mail
transportation with the first and only delivery of "Missile Mail."
Shortly before noon on 8 June 1959,
Barbero fired a Regulus cruise missile at the Naval Auxiliary Air Station, Mayport, Florida.
Twenty-two minutes later the missile struck its target; its nuclear
warhead had been replaced by two official USPS mail containers.

The USPS had officially established a branch post office on
Barbero and delivered some 3000 pieces of mail to it before
Barbero left Norfolk, Virginia.
The mail consisted entirely of postal covers (an envelope, usually with
a cachet -- a picture or story related to the event -- which postage is
canceled on the day and in the location of an historic event) addressed
to President of the United States Dwight Eisenhower, other government officials, the Postmasters General of all members of the Universal Postal Union, and so on. They contained a letter from United States Postmaster General Arthur E. Summerfield.
Their postage (four cents domestic, eight cents international) had been
cancelled "USS Barbero Jun 8 9.30am 1959" before the boat put to sea.
In Mayport, the Regulus was opened and the mail forwarded to the Jacksonville, Florida, Post Office for further sorting and routing.
